Additional External Functions - Observations/Questions: 1) Seems that ArraySave/ArraLoad function provide a way to define global variables/indicator's values and to address them when necessary: - ExtFml("PowerPivots.ArraySave",Location(0-4),GlobalVar(0-4),"69"); - ExtFml("PowerPivots.ArrayLoad",Location(0-4),GlobalVar(0-4),"69"); It's possible there are more than 4 locations to define global variables and to extract them as input for other indicators, but this is all the info I was able to identify. 2) Not clear what PivotTrigger function is performing. Looks like it takes only 2 values: +1/-1 ExtFml("PowerPivots.PivotTrigger") 3) Seems that the SysEval has the LE/SE/LX/SX/Buy/Sell signals coded as follows: LE:=100100; SE:=-100100; LX:=100300; SX:=-100300; Buy:=100200; Sell:=-100200; 4) Indicator Retracement Looks like the PlotIx it's an array of the targeted indicator values. ExtFml( "PowerPivots.RetInd", PlotIx, PivotArray, TrendArray, PivotSTRENGTH, Retrace%) Usage Question: what format should be used to initialize the argument arrays: TDataCreate/Localize or ArraySave/Load ? Anybody who had the chance to use these function is welcomed to comment and provide examples of their use. Guara Riua
