is there a possibility to open positions as soon as a certain line is crossed or directly place limit orders at a certain price level?
Taking the following situation:

As soon as the blue line is crossed, a long contract should be bought. If I use the built in sentimentor logic it's only calculated at every bar which means in this case it would buy too late.
I know there's an Intraday entry solution whs-futurestation-nano-express-programm ... -t904.html,
But it's not backtestable and therefore doesn't help me.
Is there any solution to trigger/place a buy order directly at the blue line which is backtestable?
Any help is appreciated!
Regards,
Thom
