Hi All,

I try to use « trend follower” indicator posted by robertogozzi as a simple strategy.

Original Indicator link : https://www.prorealcode.com/prorealtime-indicators/trend-follower/

Strategy is based on “trend > 0” for BUY signal and “trend < 0” for SELL signal. Strategy is coded to be LONG or SHORT.

You’ll find below the strategy, however back test result shows entry and close position don’t follow the indicator. See sceenshot also attached.

Any idea?

Thank you.

I run with PRTV11
