look nice
Can this indicator be modified to run as an explorer to identify main pivots (as in the code above) on EOD data for the last few bars?
Tried modifying but always get
aHPivs,aAddedHPivs,aLPivs and aAddedLPivs as zero value.what time frame use for crudeoil
does anyone have this for backtest ?
@kaiji, please reply, I wanted to ask you about your code
