Paul,
Sure. Look at Equis - CCI +100/-100 Crossover tester and check those
buy and sell tabs.
In the original formula you would cange the input value to and opt#
value like this:
Period:= opt1;
EMA1:= Mov(CLOSE,Period,E);
EMA2:= Mov(EMA1,Period,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA:= EMA1 + Difference;
ZeroLagEMA
Then the Buy Order is:
Period:= opt1;
EMA1:= Mov(CLOSE,Period,E);
EMA2:= Mov(EMA1,Period,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA:= EMA1 + Difference;
ZeroLagEMA
Cross(ZeroLagEMA,Mov(ZeroLagEMA,opt2,E))
Make it easy on yourself and run this with a non optimized sell then
optimize the sell side.
