I clicked on "Code Check & Profile" in the AFL editor and it
gives me the warning that my code references future quotes, "40 past and
ALL future quotes are needed to calculate the formula correctly." Hoping
anyone can chime in here with reasons why that might be happening.
Is there any other way to test if I have a "Future Leak" other than
relying on the Code Check tool?
I have gone through my FOREX trading system with a fine tooth comb and can't
find any place where it references the future. It makes use of several moving
averages that only reference the current Close, and back through the lasts 40
Closes. I test my current Close against the MAs, as well as against static
profit and stop targets.
I am wondering if my backtester settings are somehow setting off the Code Check
warning. Would any of the following backtester settings set off a false
warning of this sort? What else might trigger the 'Future Leak' alarm? I don't
use any fancy functions like ZIG, just plan old MAs...
