Dear Friends...
I want to convert this AFL trading system in to Metastock Formula Language.... kindly please help me to convert it from AFL to Metastock coding...
Thank You in Advance...

/* Just to clarify, the red and green arrows identify the pivots identified by the code.
They can be used to do things such as measuring fib time and price retracements
-- basically, recognizing a pattern in the immediate present based on the locations of swing points in the past.
These arrays are especially useful:
// -- the price values of the high pivots,
// where aHPivHighs[0] is the most recent
aHPivHighs
// -- Ditto, but for lows
aLPivLows
// -- the bar indexes of the high and low pivots,
// for identifying symmetry in retacements
