Stop loss on lowest close between two stochastic crosses

[Tajus]

I am trying to make a stoploss order to be the lowest price between the last crossunder of the Stochastic and the enter position signal of the current crossover for long (for example).

How do I recall the lowest price between these two designated crossunder and crossovers?

Best regards

Hi Tajus,

In your example, you would first need to know how many bars back the last crossunder (and crossover) happened. For this you can use the builtin "barssince" function. If you know that for example the last crossunder happened 7 bars ago, you can paste that value to the builtin "lowest" function (for example: lowest(low, 7)

I hope this points you in the right direction.

bet of luck with your coding
