I am tring to create a line to do  back test.

Goal is:

Entry is made at price C

StopLoss (SL) is C - y (y is calulated before entry and does not change)

So:

If C>C1 then SL=C-y

else SL=SL

I can get this work as a yes - no but cannot get a line. Is this possible?

Thanks

Im not sure I understand what you are asking but you could try:

ABS(C>C1)*(SL)

Plotted as a dot on the price scale.

Thanks

Whoops I missed the "else"

Something like this maybe:

Abs(C>C1)*(C-y)+ABS(C<=C1)*(SL)

Thanks
