Seems like you had a nice day today, but 20% profit is way to much for one day. It's nice when it's working but when it's not it will probably cause more scaling in and large losses. I know this is just demo but you should probably work with realistic targets and sizing so you have realistic expectations when you go live again. You should probably risk around 2% per trade max to be save in a losing streak. So with a $5K account your stop should never be bigger than $100 totally per position, even if you scale in you should never exceed that. If do that you protect yourself from a blow out when you have a losing streak yet you can still grow your account very nicely over time. Remember slow and steady with consistency wins the race. Very large profit or loss swings are almost a guarantee for failure in the long run. It seems like you are doing well the last few days, don't let leverage fuck you up again.
Why you are using sim and not market replay in this case? Via replay you can work many times more effective. Just speed up non tradable context and switch to normal speed when needed.
stop placement requires understanding of the trading conditions and also the market read. first read the market.....when you get the entry set up then see where the stop should be according to market conditions and then calculate position size.
i used market reply on holidays. i found that i could not think or act fast enough. another thing was waiting for long periods is an integral part of trading and in market replay you do not have to do that... chasing the market and not waiting for an obvious trade to set up, is what kills the trader.
for 13 years i ignored inside bars because trading around them was a little complicated.that was really a huge mistake. a range is actually an inside bar on some bigger time frame..
