[EXAMPLE] Position sizing based on pre-determined (acceptable) loss & stop-loss size

Hey fellas!

Here is an example code snippet to demonstrate how you can calculate your position size based on acceptable loss amount and your stop-loss size. You can test this code by running a backtest on the market of your choice, it will run 2 updates and output the calculated values and the actual loss amount.

The code works “both ways”, meaning that you can use this for COIN/USDT and COIN/BTC markets (or whatever the underlying asset is). The code also works in both SPOT and FUTURES.

~~May the profits be with you~~
