Hello all,
I apply this formula to OOSEQ. It helps me to better judge various systems.
PercChange=(C-Ref(C,-1))/Ref(C,-1)*100;
NormEquityPercent=Cum(PercChange);
Plot( NormEquityPercent, _DEFAULT_NAME(), ParamColor( "ColorHigh", colorCycle
), ParamStyle("Style") );
Plot( 0, _DEFAULT_NAME(), ParamColor( "o", colorCycle ), ParamStyle("Style") );
BR,
Michal
