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

Floating point has infinite number of decimals,
it's your not understanding floating point and that some numbers can't be
represented exactly. (like 1/10.)
Double-precision floating-point format - Wikipedia, the free encyclopedia - Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.
- SL/TP (stops) need to be normalized to tick size (not Point) — code fails on metals. (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 programming forum) and abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum
- 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 Metals. So do it right: Trailing Bar Entry EA - MQL4 programming forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 programming forum
- 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.
- MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.
