Displaying percentage

New comment
 

Hi; I am using this formula to calculate percentage:

Profits=NormalizeDouble((OrderProfit()/orderProf)*100,2);

 (orderProf is preset to $200).

It works fine, except it doesn't display properly:


Any suggestions?

Thanks a bunch.

 

Since it is for display purposes, use the function DoubleToString() to convert the value to a string of exact number of digits.

You used NormalizeDouble, It's use is usually wrong, as it is in your case.

  1. Floating point has an infinite number of decimals, it's you were not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)

  2. Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.

  3. SL/TP (stops) need to be normalized to tick size (not Point) — code fails on non-currencies.

  4. Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on non-currencies. So do it right.

  5. Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.

  6. MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

  7. Prices you get from the terminal are already correct (normalized).

  8. PIP, Point, or Tick are all different in general.
