Yes, I have. But I got the same error.
Here's my simple moving average crossover script for your review:
==================================================
len1 = optimize( "Short Simple Moving Average Length", 20, 5, 200, 1 );
len2 = optimize( "Long Simple Moving Average Length", 40, 5, 200, 1 );
len1 = lastValue(IIF(IsEmpty(len1), 1, len1));
len2 = lastValue(IIF(IsEmpty(len2), 1, len2));
condition1 = cross(ma(close, len1), ma(close, len2));
condition2 = cross(ma(close, len2), ma(close, len1));
buy = cover = condition1;
sell = short = condition2;
buy = ExRem( buy, sell );
sell = ExRem( sell, buy );
exclude =NOT (buy OR sell );
==================================================
sincerely,
