Hi!

I'm a fairly new user of ESignal and wondered if one of my ELA-codes (Tradestation) could be transferred to be used in ESignal.

Michael from the ESignal-Support asked me to post my question here.

Any help would be great!

Thanks a lot,
Harry

The study colors bars on a bar chart.

This is the ELA-Code:

{Name: ATRLngShrt
Notes: Paints bars based on the change of price from the lowest low or highest high
of a given period with the addition of the Average True Range

Input: BarLength - Number of bars to calculate lowest low or highest high (16 is the default value)
ATRLength - Number of days to calculate the ATR and the SMA of the ATR
}

Input: BarLength(16), ATRLength(9);
Vars: LowestLow(0), HighestHigh(0);

If CurrentBar > 1 Then Begin

LowestLow = Lowest (low, BarLength);
HighestHigh = Highest (High, BarLength);


If Close > LowestLow + AverageFC(AvgTrueRange(ATRLength), ATRLength) * 2.5 AND
Close > HighestHigh - AverageFC( AvgTrueRange(ATRLength), ATRLength) * 2.5 then begin

PlotPaintBar(High, Low, Open, Close, "LongShort", Green);

End;

If Close < HighestHigh - AverageFC( AvgTrueRange(ATRLength), ATRLength) * 2.5 AND
Close < LowestLow + AverageFC(AvgTrueRange(ATRLength), ATRLength) * 2.5 then begin

PlotPaintBar (High, Low, Open, Close, "LongShort", Red);

End;

End;

Here's what I have so far, though I'm not sure why the price bars aren't changing color. Anyone know?

Have you tried plotting
LL + ((vATR + nATRLength)/2) * 2.5
HH - ((vATR + nATRLength)/2) * 2.5
to see where they are respect to prices. It could be that the conditions are actually never met.
Just an idea
