Same code indicator , same values on different brokers but on one not showing arrows

New comment
 

Hi,

is there a particular reason why the same code of an indicator shows arrows on a broker (Darwinex) and not on another (IG)?

The signal correctly works on both brokers showing the same values but when it comes to drawing arrows on one broker it doesn't show them (the signal to trade) while on another it does.

Where am I wrong?


thanks in advance

Raimondo

 
post your code and the people may help.
 

yeah sure.. Sergey. This is the DV2 Oscillator after being transformed with a Percent Rank function.

Any help would be appreciated
