Hi Marcin,
I want to use AFL to calculate some P value on MA. Below is a formula in AFL.
WMA10 = WMA( Close, 10 ); // create 10pd WMA of Close
WMA20 = WMA( Close, 20 ); // and 20 pd WMA
Crosses = Cross( WMA10, WMA20) // mark bars with 10 crossing above 20
OR Cross( WMA20, WMA10 ) // and bars with 10 crossing below 20;
P4 = ValueWhen( Crosses, WMA10 ); // value of WMA when cross occurs
P3 = ValueWhen( Crosses, Ref( WMA10, -1 ); // and 1 bar before cross
P2 = ValueWhen( Crosses, Ref( WMA10, -2 ); // 2 bars before
P1 = ValueWhen( Crosses, Ref( WMA10, -3 ); // 3 bars before
There are several syntax errors in this formula, but I can’t solve them with my little AFL knowledge.
Could you please help me to solve this problem? Your help would be appreciated.
Best regards,
Zewen
