Draft legislation to implement the UK-EU deal now published

A few quick thoughts (although very much first

For fun I made a Robinhood account. It took me 5 minutes to sign up, get approved and transfer funds for trading...

Here's some details... Read on.

...it took me another 5 minutes to get qualified for options.

If I share a sign up I get "free shares" and I can share as much as I want up to 500$ worth.

The main UI has a prepopulated "list" of stocks/crypto to watch and links to news.

Clicking a stock opens a "trade" button that looks like this.

Notice options is first, buy second.

Options took me to an approval process (which took about a minute) and now away I go trading Baba options.

Buying stock looks like this. It emphasizes fractional shares.

THE TRADER'S EDGE: THINKING IN PROBABILITIES

Casinos make consistent profits day after day and year after year, doing something random

At the same time, most traders believe that the outcome of the market's behavior is not random,yet can't produce consistent profits

Thread 🧵

What casino owners ,professional traders know is that probable outcomes can also produce consistent results if you " Have an edge" and trade on a large enough sample size.

The best traders treat trading like a numbers game.

1. To illustrate, let's look at the game of blackjack-

In blackjack, the casinos have approximately a 4.5-percent edge over the player.

This means that casinos will make profit over a large enough sample size, even after several winning streaks and big profits of many players.

At the end of the day, week, month, or year, the casino always ends up with approximately 4.5 percent of the total amount wagered.

That 4.5 percent might not sound like a lot, but let's put it in perspective.

Suppose a total of $100 million dollars is wagered collectively at all of a casino's blackjack tables over the course of a year. The casino will net $4.5 million.

What casino owners and pro traders understand about the nature of probabilities is that each individual hand played

THREAD ON DELTA (The most important GREEK)

Many traders don't indulge in understanding GREEKS because they think they are very complicated.

There are 4 primary greeks:

Delta
Gamma
Theta
Vega

In my experience, understanding DELTA is enough to take benefit of greeks.(1/n)

Delta measures the rate of change of options price based on the directional movement of the underlying.

So this means we can know in advance (theoretically) how much an option will move with the underlying & so we can prepare our strategies accordingly. (2/n)

Value of delta varies between 0 & 1 for calls and -1 & 0 for puts. This figure tells how much an option price will change, when the underlying moves 1 point. So example a delta of .2 of call indicates that for every 1 point change in the underlying, the price will move .2 (3/n)

For option writers who want to trade in neutral strategies like straddle, strangle, ratios, calendar etc, delta can be very helpful. So be it any complex strategy, knowing the NET DELTA can give you an idea of how your strategy will perform in different scenarios. (4/n)

Net delta is just the sum of the deltas of all the bull options (call+ & put-) minus the bear options (call- & put+).

So if we can track this, we will always be in the know of how much exposed our position is. It makes it easier then to adjust our position. (5/n)

#NIFTY

Bearish engulfing on monthly or bullish harami on Weekly , which one will play out?

Outlook for the week Jan 2 - 6, 2022.

THREAD: Deconstructing NIFTY on 5 different TF's.

#NIFTY

1. Monthly TF:

• Although the structure in monthly TF is of HH-HL, December monthly candle is a more of a bearish engulfing.

• However it is exactly at the support

• 17800-18000 looks like a strong support.

#NIFTY

2. Weekly TF:

• 17800- 1800 used to be a resistance in April & August 2022.

• However post BO of those levels, they might act as an immediate support.

• Current weekly candle is closer to the support (erstwhile resistance)

#NIFTY

3. Daily TF:

• After a sharp vertical fall, we expected a buying momentum

• Also Nifty filled the Gap.

• Strong support at 17800

#NIFTY

4. Hourly TF:

Moving within the rising channel, albiet the channel is quite steep.

Working on some execution optimisation related backtesting. I have so far been executing with market orders only. Going towards higher lot sizes, I'd like to optimise for minimal slippage.

First off, on NSE, if you place a market order, you get filled at the best bid/ask right?

If we want to optimise this, the first non-creative idea one can think of is, slicing the order into different lot sizes, and placing a limit order for each slice at the mid point of current best bid & ask.

But this requires your latency to be the least.

Why would latency affect it?

I looked at tick historical data, and there are more than 18-20 ticks in a second (auction and quote combined).

Even if you keep 10 ticks per second, your best bid/ask can shift from the time you place to the time exchange receives the order.

So, the next best thing that people can do is place tranches of orders every 1s, 3s, 5s, 10s, 15s - in their preferred time range, and get filled at the midpoint or best-bid+1/2/3/4/5 in the depth.

What you need is liquidity.

But if you're trading breakouts, then it's highly likely that your limit orders may not get filled if the action is too fast.

So, a retry mechanism is required in such cases.

If nothing works, you convert your orders to marketable and get filled at worse slippage.
