Maths question and MT4 compiler/tester issue?

Is that your interpretation or your literacy is not good enough and is seeking advice?

My literacy is fine and my interpretation is correct.

Very interesting maths from everyone, thank you. I'm going to try some of the distilled ideas. The comment about the compiler rounding in order makes sense. All the variables are doubles based on ******* but with the divisions it may be more consistent with Normalizing the variables. Thanks to everyone. Did not expect all those replies and calcs. There are a lot of closet mathematicians here on FF!

Yahoo , normalizing doubles, I think I won the first prize

OK did some quicks tests...as far as the tester based on my backtested data...

0.125 * (A + B + C + D + E + F + G + H)
Equals
(2.5*A + 2.5*B + 2.5*C + 2.5*D + 2.5*E + 2.5*F + 2.5*G + 2.5*H) / 20

The above is as expected...

HOWEVER...although the two formulas above give the same result, they give a different result from the raw formula below, and give the same calc as the 2nd raw formula below...must be either a rounding issue or a weird datapoint on the either of the variables.

(A + B)/2
+ (C + D)/2
+ (E + F)/2
+ (G + H)/2
+ (A + B)/2
+ (C + D)/2
+ (E + F)/2
+ (G + H)/2
+ (A + D)/2 + (B + C)/2
+ (A + F)/2 + (B + E)/2
+ (A + H)/2 + (B + G)/2
+ (C + F)/2 + (D + E)/2
+ (C + H)/2 + (D + G)/2
+ (E + H)/2 + (F + G)/2


The distilled formulas equal the formula below...
(A + B)/2
+ (C + D)/2
+ (E + F)/2
+ (G + H)/2
+ (A + B)/2
+ (C + D)/2
+ (E + F)/2
+ (G + H)/2
+ (A + D)/2 + (B + C)/2
+ (E + H)/2 + (F + G)/2
+ (A + F)/2 + (B + E)/2
+ (A + H)/2 + (B + G)/2
+ (C + F)/2 + (D + E)/2
+ (C + H)/2 + (D + G)/2

I will keep these calcs in mind, but since the raw un-normalized divided numbers actually tested better, I'm going to try those, until there is a problem in live trading with them. As soon as there is a glitch in live trading with the formula, I'll try normalizing all divisions and then going with the least common denominator. I really like this one the best...

0.125 * (A + B + C + D + E + F + G + H)

some people always wanna touch their nose via rounding the head ...
