Module 3-B (Bonus)

In this Bonus Module, I will attempt to teach you how to write an algorithm to create a Stock Screener based on @markminervini 's Trend Template from his book Trade Like A Stock Market Wizard.

+

 Some of the readers asked about how to create a stock screener. So, I thought before jumping to the cloud and deploying an algorithm on the cloud, I should address this. Whatever algorithm we develop in this module, we will deploy it on the cloud in Module number 4.

+
Pre-requisites:

• Read Module 2, so that you can download the historical data. A small assignment for you - write code to automate EOD data download and save it in the folder. We need to have the latest data for the screener. Hint: set end_date = https://t.co/u2N2I53cm4()

+
The rules are:

• The LTP of the stock > 150 SMA & 200 SMA
• The 150 SMA > 200 SMA
• The 200 SMA must be greater than 200 SMA 30 days ago.
• The 50 SMA > 150 SMA & 50 SMA > 200 SMA
• The LTP > 50 SMA
• The LTP must be greater than 30% of 52-Week Low

+
• The LTP is close to 25% of the 52-Week High
• The Relative Strength(RS) should be greater than 70

SMA = Simple Moving Average
LTP = Last Traded Price

Let's get started with its coding.

+
We are going to use pandas and pandas_ta library.

+
Then we define the universe on which we are working. This universe is the same as that defined in Module 2.

+
DATA_BASE_FOLDER is the folder where your data is saved. This varies and will be different for you. Then, you define a data frame cols with all the parameters: Stock Name, LTP, RSI, 50,150, 200 moving average, 200 moving average 20 days ago, 52 weeks Low and 52 weeks High

+
We also define the main Dataframe MarketWatch that holds all the data on which we will do our calculation. Let us call it MarketWatch.

+
Then you iterate through these stocks. In order to calculate RSI, Simple moving average we use pandas ta library. It is very simple to use these functions, just call these functions ta.rsi, ta.sma .

+
Note that, when you use the above functions it returns a series. You have to fetch the latest value so access the latest value by using -1.
To calculate 52 weeks high/low, I assume that there are on average 253 trading days in a year. If you take 365 days, results will vary.

+
Finally, we create a temporary data frame df2 and append it to the Marketwatch. Finally, the market watch looks like this. 70% of our job is done. Next, we just need to write some conditions over this MarketWatch and identify all the stocks that satisfy the screener conditions.
+
Let's iterate through all the stocks in the Marketwatch. We have a variable isStockFiltered which is set to False if it fails any of the 7 conditions for the screener.

+
We check for all the 7 rules we stated above from Mark Minervini's template. If a stock fails to match any of the conditions, we reject that stock entirely. If it matches the condition, we say that the stock has met the requirement.

+
Unfortunately, in the current market scenario and worldwide market corrections, there is no stock coming under the screener for buy. If you comment out some of the conditions you may see some stocks coming, say I remove condition sma50 > sma150 > sma200 and then I see

+
some stocks are being thrown by our screener.

Note: This module will help you understand that there are details to anything to use in your trading voyage. For e.g. you may use 365 days instead of 253 to calculate 52 weeks high/low. You should also understand the underlying

+
formula on how you calculate RSI, SMA, etc. But, more than anything, you should educate yourselves so that no one can fool you into selling you random magic indicators.

Module 3

In this post, I will attempt to teach you how to write an algorithm in python to automatically find support and resistance. We shall use the data we downloaded in module 2.

+

To visualize price action, I have used the daily candlestick chart. To quantify the meaning of support and resistance, I have taken below definitions:
In a series of 5 continuous candles, if the first three candles make increasing high and then 2 decreasing highs, then the

+

high of the third candle is considered resistance. Similarly, if the first 3 candles make lower lows and the next 2 make high lows then the low of the third candle is support.

+


The above explanation is for the sake of quantifying support and resistance at a very basic level. These are called fractals. Now let's get started with the code.

mpl_finance is the new module here. We will use its candlestick_ohlc function.

+


Now, if you remember, you downloaded data for nifty 50 stocks in module 2. We shall use that data. Let's work on ITC data this time.
We will use data from 1 Jan 2021 to 30 June 2021.

Module 4

In this post, I will attempt to teach you how to write a trading strategy in Equity Segment that runs on your PC and create a Telegram bot that sends you buy/sell signals with Stop Loss.


Prerequisite: If you hadn't gone through the earlier modules, I strongly recommend you go through them all. Module 2: https://t.co/pciDOJXyVI

Note:
If you liked my content, you can donate, tip and support me on this link (any amount you prefer)


We are going to implement below strategy:

Rules: There should be three candles -> high of candle 1 > high of candle 2 > high of candle 3 and low of candle 1 < low of candle 2 < low of candle 3, where candle 3 is T-1 day, candle 2 is T-2 day and candle 1 is of T-3 Day, T = today.


If on today(day=T), the stock crosses yesterday high(candle 3), then send a buy signal to your telegram handle with candle 3 low as SL.

Before we get started with code, let's create a telegram bot using BotFather.

Step 1: Search BotFather in the telegram.
Step 2: type /newbot and then give the name to your bot. Refer to the second image as an example

Fake chats claiming to be from the Irish African community are being disseminated by the far right in order to suggest that violence is imminent from #BLM supporters. This is straight out of the QAnon and Proud Boys playbook. Spread the word. Protest safely. #georgenkencho


There is co-ordination across the far right in Ireland now to stir both left and right in the hopes of creating a race war. Think critically! Fascists see the tragic killing of #georgenkencho, the grief of his community and pending investigation as a flashpoint for action.


Across Telegram, Twitter and Facebook disinformation is being peddled on the back of these tragic events. From false photographs to the tactics ofwhite supremacy, the far right is clumsily trying to drive hate against minority groups and figureheads.


Declan Ganley’s Burkean group and the incel wing of National Party (Gearóid Murphy, Mick O’Keeffe & Co.) as well as all the usuals are concerted in their efforts to demonstrate their white supremacist cred. The quiet parts are today being said out loud.


The best thing you can do is challenge disinformation and report posts where engagement isn’t appropriate. Many of these are blatantly racist posts designed to drive recruitment to NP and other Nationalist groups. By all means protest but stay safe.

दधीचि ऋषि को मनाही थी कि वह अश्विनी कुमारों को किसी भी अवस्था में ब्रह्मविद्या का उपदेश नहीं दें। ये आदेश देवराज इन्द्र का था।वह नहीं चाहते थे कि उनके सिंहासन को प्रत्यक्ष या परोक्ष रुप से कोई भी खतरा हो।मगर जब अश्विनी कुमारों ने सहृदय प्रार्थना की तो महर्षि सहर्ष मान गए।


और उन्होनें ब्रह्मविद्या का ज्ञान अश्विनि कुमारों को दे दिया। गुप्तचरों के माध्यम से जब खबर इन्द्रदेव तक पहुंची तो वे क्रोध में खड़ग ले कर गए और महर्षि दधीचि का सर धड़ से अलग कर दिया।मगर अश्विनी कुमार भी कहां चुप बैठने वाले थे।उन्होने तुरंत एक अश्व का सिर महर्षि के धड़ पे...


...प्रत्यारोपित कर उन्हें जीवित रख लिया।उस दिन के पश्चात महर्षि दधीचि अश्वशिरा भी कहलाए जाने लगे।अब आगे सुनिये की किस प्रकार महर्षि दधीचि का सर काटने वाले इन्द्र कैसे अपनी रक्षा हेतु उनके आगे गिड़गिड़ाए ।

एक बार देवराज इन्द्र अपनी सभा में बैठे थे, तो उन्हे खुद पर अभिमान हो आया।


वे सोचने लगे कि हम तीनों लोकों के स्वामी हैं। ब्राह्मण हमें यज्ञ में आहुति देते हैं और हमारी उपासना करते हैं। फिर हम सामान्य ब्राह्मण बृहस्पति से क्यों डरते हैं ?उनके आने पर क्यों खड़े हो जाते हैं?वे तो हमारी जीविका से पलते हैं। देवर्षि बृहस्पति देवताओं के गुरु थे।

अभिमान के कारण ऋषि बृहस्पति के पधारने पर न तो इन्द्र ही खड़े हुए और न ही अन्य देवों को खड़े होने दिया।देवगुरु बृहस्पति इन्द्र का ये कठोर दुर्व्यवहार देख कर चुप चाप वहां से लौट गए।कुछ देर पश्चात जब देवराज का मद उतरा तो उन्हे अपनी गलती का एहसास हुआ।

Keep dwelling on this:
Further Examination of the Motif near PRRA Reveals Close Structural Similarity to the SEB Superantigen as well as Sequence Similarities to Neurotoxins and a Viral SAg.

The insertion PRRA together with 7 sequentially preceding residues & succeeding R685 (conserved in β-CoVs) form a motif, Y674QTQTNSPRRAR685, homologous to those of neurotoxins from Ophiophagus (cobra) and Bungarus genera, as well as neurotoxin-like regions from three RABV strains

(20) (Fig. 2D). We further noticed that the same segment bears close similarity to the HIV-1 glycoprotein gp120 SAg motif F164 to V174.

STORY OF PURANAS AND SUB PURANA (उप पुराण).

We have already gone through the series on importance & characteristics of all the eighteen Purans. We also know that originally there were hundred crore shlokas but were divided by Vyas in each Kalp and was compiled as eighteen Purans


for the common people to understand it properly and now their total is about four lakhs.

In Brahm Puran, Brahma preached this to Marichi. So this Puran of ten thousand shlokas is called Brahm Puran.

In Padma Puran, the base of the story is the appearance of Brahma on a lotus(Padm) from Vishnu' s navel.This has fifty five thousand shlokas.

Vishnu Puran is primarily based in Varah kalp. This book is on Vishnu and this book has twenty three thousand shlokas.

Vaayu Puran is written in Shwet Kalp and has twenty four thousand shlokas. Here Vayudev preaches about Dharma.

In Bhagwat Puran, which is written with the base of Gayatri mantra describes Dharma extensively. It has 18000 shlokas. It also mentions the story of Vritrasur.

In Narad Puran, which has twenty five thousand shlokas, is a sermon on Dharma by Narad based in Brihad Kalp.

Markandeya Puran has nine thousand shlokas and here it is through the birds that Dharma is described.
