Hi Geoff,
Thank you for posting the formula.
As for ExRem() - it needs a valid sell rule to work.
You can not use it is when sell condition is always FALSE
(sell = 0 ) as in your example.
ExRem( triggerarray, resetarray ) works as follows:
1. returns true on first bar that is true on trigger array
2. returns false until there is a non-zero value in the second array
3. repeat step 1
triggerarray =
0,1,1,1,1,0,1,1,0,0,0,0,1,1,0,1,0
resetarray =
0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0,0
ExRem() =
0,1,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0
Best regards,
Tomasz Janeczko
