Also, what's your approach to risk management?

For example:

1. Do you have anything that limits the size of a single trade or position?

2. How do you measure and manage overall volatility/risk/VAR to your portfolio?

3. What kind of safeguards do you have to avoid catastrophic bugs? (For reference, see Knight capital and how a single bug brought down the entire company: https://www.henricodolfing.com/2019/06/project-failure-case-...) Given how fast your system trades, I imagine it must be difficult to visually spot these errors. (You did mention paper trading, but I wonder if you have anything else you want to mention)

Thanks so much for sharing your knowledge publicly. It's very much appreciated!

Here's some simple rules. I basically just read about these and then stole the ideas. I wish I had data to back this up and it seems to be working.

- No single bet can be more than 5% of all money. The small bet sizes are what really saves your bacon in that even if a few lose 10+% you're still fine overall. - I'm also limiting the amount of shares I bet and try to keep it in the low hundreds so that I get really fast fills. - I have something that stops everything if I lose more than 1k in a day.

I don't do anything to measure overall risk or volatility. Almost everything I'm in is highly volatile. I'm basically betting as things go up and then try to cash out. Sometimes you hit the top.

Yeah, I inspect all the trades at the end of the day, well and during the day, and try to feed anything new back into the system. This is 100% manual. But, like if a single trade loses $100 or something definitely I'm in there looking at what happened.

Thanks!

What is your 'win' rate? (Percentage of trades that make money as a fraction of overall trades)?

How many trades does your system make on average in a given day?

Do you hold positions overnight?

Around 45-50% win rate but I try and keep the runners going for as long as possible and exit out of the loser trades quickly (this basically just costs you the commission on losers but sometimes more). You can tell within a minute or two if what you expect to happen is going to happen. So, even with a 50/50 win/loss rate you can still make money. I make around 100-200 trades per day. Sell everything before market close.
