One of the many paradoxes of trading in markets is that - for a given period of time - strategies that are ‘right’ in the broader time context can be absolutely catastrophic in other times. Indeed, careers of one or two currently lauded by FinTwit and the wider financial media

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.

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.

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.

How to save tax when income is above 50 lakhs?

Here are 9 benefits of trading in a corporate account: 🧵

Collaborated with @niki_poojary

1. Make a Pvt Ltd Company.

Form a company with family members and trade under it. The family members should be directors of the company. Will explain why later.

Why form a company?
You will only need to pay 25% flat tax. Individuals have to pay 30% tax above 10 lakh profits.

2. Surcharge Benefits:

You will be charged a lower surcharge in a corporate account.

Check the picture below:

Total Tax Outlay:

The total tax outlay for individuals is 30% plus surcharge. If you really earn a lot (10 cr +) then you will be paying 42% tax.

Whereas in a company you'll be paying a maximum of 28% tax.

This is how rich people save a lot of their money by paying low taxes.

3. Expenses can be deducted.

All expenses can be deducted from a company account.

Companies:
1. First make a profit.
2. then deduct the expenses
3. & Pay tax on the remaining income

Individuals:
1. First Profit
2. Then Pay tax
3. Expenses with whatever is left.
