Use NormalizeDouble without round the number

[web11]

Dear,

I wrote the code below.

int LOT_PRECISION=2;
sLots = 0.02;
Multi = 1.83;
double mLot = NormalizeDouble(sLots * Multi,LOT_PRECISION);

So actually calculation is  0.02*1.83=0.0366   and i want only 2 digit without round the number like = 0.03 just leave "66"

but above coding mLots show 0.04 coding make it round. i don't want round. is anyone help me how i make code function return double value with 2 digit without round the number.

Thank in Advanced

Normalize your lot correctly :

You have either to use OrderLots() to close a full position or

to normalize your lot size this way :

      double lotStep=SymbolInfoDouble(_Symbol,SYMBOL_VOLUME_STEP);
      lots=MathRound(lots/lotStep)*lotStep;

If you don't want rounding, just use MathFloor() instead of MathRound().

Do NOT use NormalizeDouble, EVER. For ANY Reason. It's a kludge, don't use it. It's use is always wrong

• SL/TP (stops) need to be normalized to tick size (not Point.) (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 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 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 forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 forum
• Lot size must also be adjusted to a multiple of LotStep. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.
