Thread: Parabolic SAR Indicator

Parabolic SAR (PSAR) indicator was developed by J. Welles Wilder.

#PSAR #Indicators #Definedge

 The calculation of this indicator is a bit complex, but the concept is extremely useful. I will try to simplify it and explain the logic. I will briefly explain the concept, calculation and reading.

Let us think about creating an indicator that shows the trend.
Using the indicator, we can identify & ride the trend using the trailing stop-loss method.

For trailing the stop in uptrend, indicator needs to be placed below the candle. Similarly, it should be placed above the candle for trailing in a downtrend. We will plot it using ‘dots’.
So, the indicator & stop-loss will be rising in uptrend & falling in downtrend.

Let us define the trend as:

If Low of the candle > Stop-loss level in bull market = Trend remains bullish.

If High of the candle < Stop-loss level in bear market = Trend is bearish
Imagine you are driving a car on highway; you would like to accelerate if the road is clear. You will slow down if the road is bumpy.
Same concept is applied here.

The indicator rises steadily if the trend is steady. If the trend is strong the indicator should accelerate, it should move faster and stop should get trailed aggressively.

What is strong trend?
Strong?
In a bullish trend if price makes a new high it is a strong bullish trend.
In a bearish trend, if price makes a new low it is a strong bearish trend.

Period?
Period for new high: since the indicator turned bullish
Period for new low: since the indicator turned bearish
Hope concept is clear.

Calculation of PSAR: EP, AF and PSAR

Extreme Price (EP) is calculated on every candle.

‘High’ price in bullish market and ‘Low’ price in bearish market is called as Extreme Price (EP).
If Bullish trend:

If new high is made -> EP = New High price
Else
EP = Prev High

If Bearish trend

If new low is made -> EP = New Low price
Else
EP = Prev Low

Period of new high or low is explained earlier.
Wilder created a method of calculating Acceleration Factor (AF) for the indicator:

> Accelerate it by 0.02 if trend is steady.
> Add 0.02 to previous speed if trend is strong.
> Maximum acceleration will be 0.20.
A = Different between extreme price and PSAR indicator price

Multiply Acceleration factor by A and add it to the previous stop-loss, you get new PSAR indicator reading.

PSAR = A x AF + Previous PSAR reading
Have a look at below image. Pink dots show PSAR indicator.

Phase A is when indicator moving at a steady speed. Phase B is when trend is strong (New high in bull market, new low in bear market) hence, PSAR is accelerating with a greater speed (0.02 being added) during B.
So, the basic reading of the indicator is:

Trend is bullish when price is above the PSAR, it is bearish when price is below PSAR. You can use it as a trend filtration method.

Indicator accelerates during strong trends. Hence, rising PSAR and Falling PSAR are also important.
The indicator is also used as a Stop & Reverse (SAR) trading system.

When trend changes, the length of the stop-loss depends on the previous high or low. Avoid the signal if initial stop-loss is not affordable. Wait for the pullback pattern that provides better risk-reward trade
I wouldn’t say PSAR is a good sup-res indicator because it’s a mathematical calc. But it offers pullback trade opportunity with better risk-reward when price comes near the indicator during strong trends.

It can be used alone or combined with other studies to design the system.
We discussed about AMA and Super trend indicator which uses similar concept. They go flat when trend is not strong. PSAR increases steadily if trend is not strong and moves fast when it is strong.

Below are some Important things about PSAR indictor:
Imp features:
• Unlike many other indicators, you do not have to define the look-back period, define the acceleration factor
• It does not use method of averaging
• It uses high, low prices to determine the trend and stop-loss level
• Indicator accelerates if trend is strong
Indicator is useful & applicable on different timeframes. 0.02 and 0.20 are recommended settings to being with. I like to explore it on Noiseless charts, objective price patterns are advantage there. Change max AF to 0.10 if you want to use it in Renko. I will talk more about it.
Is it a ‘leading’ or ‘best’ indicator? Its different & useful. ‘Leading’ comes at a cost, ‘Lagging’ can b useful as well. Major issue wid learning in d field of trading is that everything is associated wid trading it immediately. Focusing on concept would bring long-term success!

Thread: Camarilla Levels

Continuing our discussion on pivot levels, we look at the Camarilla levels which is another widely followed tool.

Word ‘Camarilla’ is borrowed from Spanish. It translates to a group of confidential & private advisers of the King or person in authority.


The Camarilla equation was first developed by a bond trader named Nick Scott in 1989. It is said that he didn't disclose the equation, but people studied the levels & reverse engineered it to find the formula. There r different versions of this formula.

We discussed about ‘Range’ in the earlier thread. The range is basically the difference between High & Low of the session.

High – Low = Range of the session
Continuing with the same levels as an example, If High of the day is 105 and Low is 95, Range of the session is 10 points.


Range shows us activity during the session irrespective of the trend.
Narrow range = Not much movement
Wide Range = Strong activity

Camarilla calculation depends on the Range of the session.

Let’s expand the range to 110%. If Current range is 10, let us make it 11.


Let’s now divide this Range in four parts.

9.17%, 18.33%, 27.50% and 55% of the range.

So, if Range is 10 points:
10 x 9.17% = 0.92
10 x 18.33% = 1.83
10 x 27.50% = 2.75
10 x 55% = 5.50

Thread: Alligator indicator

#Alligator #Indicators #Definedge


Alligator indicator is created by Bill Williams. He was a popular trader and author.

Before we discuss the indicator, let us understand an important concept.

Here is a chart showing 10 day moving average at bar A. Price of the stock is 100, Moving average price is 90.


What if we shift this moving average to 5 bars further? See the chart below.

Moving average at bar B is moving average price of bar A (5 candles behind). This is shifting of moving average price. What does it mean?


Simple explanation is – shifting the moving average can help one compare current price with past period moving average easily. It results in smoothening instead of increasing the moving average parameter. This is also known as Forward Displaced moving average.

Back-testing of some candlestick patterns 🧵

I hv back-tested patterns shown below on 500 stocks (Nifty 500 stock group as on today) since inception on daily timeframe charts.

Below is some interesting information.


I was doing to design multi-chart setups. But the information in the thread can be useful for people practicing candlestick chart patterns. There are many patterns & we keep coming across more. The data can give you a rough idea about the past performance of patterns.

Patterns are defined based on the popular rules of identifying them. I have also tested bearish patterns for bullish trades and vice versa (Contra approach).

Criteria: Hit ratio & returns of pattern giving 1:1 risk-reward if the entry is at the closing price of the pattern.

Some top bullish patterns have below hit ratio:

Inverted Hammer or Shooting Star – 74.72%
Multi-Harami breakout - 65.23%
Bullish Harami cross – 64.6%
Bullish Kicker – 63.53% (Got better returns)
Bullish separating line – 61.69% (It has got better returns)


Doji breakout hit ratio is decent (63.71%) but occurrences are v high so need more confirmation.

Engulfing and Harami patterns have got better returns when traded at next candle of confirmation.

Thread: Darvas Box Theory

#Darvas #knowledgesharing #Definedge


Nicolas Darvas (1920 – 1977) was a professional dancer and he travelled around the world. He founded a Dance company in 1950s. Someone offered him shares against his Dance programme and that is how he came across stock market and the business of trading.

He reportedly turned thousand dollars into millions in the late 1950s.

He wrote a popular book during 1960 “How I made $2000000 in Stock Market” in which he explained his Box theory. It is a must read.

He used a combination fundamental and technical approach for investing.

He believed in investing in only growth stocks. I think he did not explain a few things in his book, and I found some difference in interpretation of box-theory at various places because of that. This post is my interpretation of his theory.

Darvas was tracking stocks only making new high. I do not think he really talked about 52-week high. He mentioned about stocks breaking 2-3 year high. But 52-week high is mostly tracked for this theory so let us keep it that way to begin with for the sake of objectivity.

Earnings trades are not for everyone, as they involve high amounts of uncertainty and random movements.

Technical Analysis Masterclass- Part 2

'Entering the trade'

Entering a trade without ascertaining a certain things is gambling.

In this masterclass we will learn the pre-requisites to enter a trade.

DON'T ENTER A TRADE WITHOUT DETERMINNG THE FOLLOWING.

Please share.

We understand what reward to risk (popularly called risk to reward) is.
It will be denoted by R:R.

We will also try to bust a few myths about R:R and how to avoid losing trades.

Before entering a trade, you need to determine 3 things.

1. Entry trigger
2. Stop loss
3. Target

1. Entry trigger = Reasons for entering a trade. There could be multiple reasons or a single reason for entry.

Generally a set of reasons AKA confluence is a higher probability trade and a generally a safer entry.

Example of an entry trigger.


2. Stop Loss.

The price in the opposite direction of the trade where the trade is exited, at a loss.

At this level, the reason for the entry becomes invalidated according to TA and the price can then move in the opposite direction, probabilistically.


3. Target is the possible price level that the asset might touch based on previous trends or confluence AND where a possible reversal could occur.

Target is the next path of least resistance from where the price might reverse.

We will always ONLY use TA to determine all 3.

If u are looking to enter a scrip just before the breakout
what would u look for?
How would u identify scrips just before breakout?

Here are a few pointers
Carefully understand the them and use at ur own discretion
(All comments r compiled from a question i posed)

1/23

Price is testing the same resistance repeatedly since long.
But now in recent times it's forming multiple candles near the same resistance with low volume.
Observe it and see for opposite move.
As soon as u get a positive candle, get in to it.

2/23

1. Volume buildup (vol > when resistance point created) along with, increase in OI, increase in delivery % on HTF
2. On LTF, price stalling around breakout area for at least 1-2hr.
3. No major events.

3/23

Stock reaching breakout LVL with HL-HH
Contraction of price and volume near it especially near 20 days ma.
If there is any breach of the latest HL it should be followed by a bullish candle with good volume.
Left side of the chart has a rally with a very steep slope of ma.

4/23

Number of wide range green bars with high volumes.
If stock is at its ATH then it adds more conviction bcz there wont b supply after that point

Consolidation below the resistance, volume of the candles & strong bullish candle closing at near highs just below the resistance

William's Alligator is probably the most underrated indicator in moving average category.

Alligator follows the premise that market is sideways for 70% of the time and trending only 30% of the time.

This is where William's Alligator can be a great tool for traders.


Why William's Alligator can be a great tool for traders?

It can identify Bullish, Bearish and Sideways market pretty easily. Problem is, traders don't know how to use it effectively. Alligator has three lines:

1. Lips - Fastest Line
2. Teeth
3. Jaws - Slowest Line


Book Interpretation is when Lips Crosses above Jaws, it's a buying opportunity and when below its a shorting opportunity. And when three lines are crisscrossing, instrument is sideways.

BUT this does not make it a tradeable indicator in practice. Here is what should be done.

Firstly, when all the Alligator lines are moving up or down and are widening, this phase is called "Alligator eating with its mouth wide open". When the lines are crisscrossing, this indicates the alligator is sated.

Now, how to use it? with Basic TA and Indicator like MACD

Rules to remember:
1. As long as price is above Alligator, BANKNIFTY is bullish.
2. As long as MACD is trading above 0 line, BANKNIFTY is bullish.
3. Horizontal Lines are the only S&R.
4. CONGESTION is followed by TREND is followed by CONGESTION.

Most of the successful traders here are option sellers.

Ever wondered why?

Why we have chosen option selling?

Find our below

1: Being wrong and still making money.

We as option sellers can be wrong with our market view and still end up making money because of the power of theta decay and adjustments to some extent.

Adjustments work better as get closer to expiry since decay is the highest.

2: Theta decay

The biggest reason and one of the prime reasons is the theta decay.

Option sellers always have an advantage because the as time passes, the option premium falls even if the underlying instrument doesn't move.

3:Playing directional view

Option selling also enables us to take a directional view. In fact, directional view along with theta decay makes it a solid combination.

Debit spreads and credit spreads works great for a directional view.

4: Playing Neutral view

We can make money in option selling even if the market doesn't move as the otm options will go to 0 with the help of theta decay. It's the most fascinating thing.

This is what attracted many into option selling.

He has been wrong (or lying) so often that it will be nearly impossible for me to track every grift, lie, deceit, manipulation he has pulled. I will use...

@FionaPearman @ScottMorrisonMP Morrison is our statue of unempathic neoliberalism - erected by evangelical and corporate Australia to celebrate their victory over compassion, equality and secular humanism. 

Hopefully it gets pulled down like the statues of dubious heroes of oppression from an earlier age.


@ScottMorrisonMP The two-party-preferred system in 
Australia politics isn’t working for people, and it sure isn’t working for the planet.

@ScottMorrisonMP My collapse of faith in our democracies isn’t an accident. It’s one of the central victories of the neoliberal project, delivered through two generations of privatisation, outsourcing and deregulation, underfunding of government services (locked in by tax cuts),...

@ScottMorrisonMP restricting freedom of information, targeting whistleblowers and raiding the media who report on them, delegitimising and gagging public interest advocacy, and criminalising protest.

@ScottMorrisonMP Politics in Australia today relies hugely on the fact that most people don’t know most of what’s going on so as to get away with stuff that couldn’t be done under real scrutiny we have seen a clear example of this with the National Coronvirus Cabinet.

Hello Dear Tweeples!

It’s Siddhars time of the week! Last week I shared story of Guru (Machamuni or Yogi Matsyendranath), this week I bring you information on his Shishya.

#Thread on Gorakanathar Siddhar.

@LostTemple7


His origin story is interesting, though I couldn’t verify it’s authenticity, so not sharing the story here. He’s shishya of Machamuni Siddhar and also learnt from Agasthiya Siddhar.

@HelloNNewman @RajiIndustani @Kishoreciyer1

Unlike other Siddhars, he is depicted as either with a Tiger or seated & wearing Tiger skin. While I couldn’t find any explanation for this. My interpretation is as follows:

Tiger is a predator that lurks around and attacks unexpectedly.


Our 5 indriyas and 5 vikitis also similar to Tiger, they lurk around and attacks our thoughts when we’re least expecting. Gorakkar is said to have mastered these aspects, thus to denote this, he shown with Tiger.

@Itishree001 @VarierSangitha @jananisampath

Gorakanathar or Gorakshnath (as he’s known in the Nath Sampraday) is celebrated Guru in both Northern and Southern part of India. He’s one of the NavNath in Nath Sampraday and also 18 Siddhars of Tamil tradition. During his life, he’s travelled Indian subcontinent extensively +

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.
