Hi,
I'm new and and I try to learn by creating a simple algo. The algo should buy on stochastics signal (cross under classic 20 threshold) and sell only if the PNL of the trade is > to a % defined.
1. When I run the algo and I export the trades I noted that the exit conditions is not always respected (PNL < 2% for some trades). Why please ?
2. Also I would like to run it on 10 securities. I understand that I need to add securities and then lool to create the stochastic for each security. Can someone give me an example to create sur a loop please ?
3. Last, I would like to try other timeframe especially 30 minutes. How to do it with consolidator please ?
Thank you
JF
