Paint bar of Rate of change of a moving average

[mclargo]

Hello all,

Trying to convert Easylanguage code to EFS.

1. Need Rate of Change of an Exponential MA of a variable length that the user would define.
2. If Rate of change is positive, would put a small green dot on bar
3. If Rate of change is negative, would put a small yellow dot on bar.

Thanks and the Easylanguage code is below if you need it.

MC

Input: Price(Close),Length(20),RC(1);

Condition1 = RateOfChange((XAverage(Price, Length)), RC ) > 0; {Up Slope}
Condition2 = RateOfChange((XAverage(Price, Length)), RC ) < 0; {Down Slope}


value1 = H - ((h-l)/2.1);
value2 = L + ((h-l)/2.1);

PlotPaintBar(value1, value2, "PriceBarMA");

If Condition1 Then
SetPlotColor(1, Green)
Else
If Condition2 Then
SetPlotColor(1, Yellow);

loomis,

many thanks. it worked like a champ. learning efs ain't easy, but you are definitely making the learning curve less painful.

it would be nice if i could change the size of the shapes like in ts 6.0. the sizesmake all the shapes a bit intrusive, but i'm not complaining.

thanks again,
largo
