Roc indicator + x

 

Hello,

in mql4 it's not a problem, but maybe some has a solution in mql5 for the following topic: a standard built in ROC indicator (line) should get two kinds of arrows (green and yellow) placed on those ROC line values, when an external (custom) indicator touches a certain value. So, if the external indicator was RSI it would be: if (RSI >= 0.7) show on those bars in the chart a green arrow on the ROC line, if (RSI <= 0.3) show a yellow one. For potential hints how to get this done, thanks a lot in advance.
