Following a previous discussion and your message in another thread (, let's try to implement COT for Sierra Chart.
As you explained me...
COT High cumulates the delta (ask volume minus bid volume) in the bar tick after tick (trade after trade). But it is reset to 0 on the tick which is:
(i) either a higher high (within the bar)
(ii) or a repeat of the former high of the bar
COT Low cumulates the delta (ask volume minus bid volume) in the bar tick after tick (trade after trade). But it is reset to 0 on the tick which is:
(i) either a lower low (within the bar)
(ii) or a repeat of the former low of the bar
COT is similar to the pullback column.
The main difference is that pullback column is only reset in the situation (i) and not each time the H/L is repeated.
