i have a buy order ...that has a stop loss of 1.5 times the ATR (the atr_stoploss_modifier=1.5)
lets say i am trading the EURUSD with a 5 digit broker.
does the stoploass need to have 5 digits exalctly ?
if it has more digits (because when i multiply the atr value with 1.5 it can produce a stop loss with 6 digits)...will it trim it otomaticaly and accept the order?
i have to use NormalizeDouble() function
atr_stoploss_modifier=atr_stoploss_modifier/MarketInfo(OrderSymbol(),MODE_POINT); // 1.5 convert Pips
NormalizeDouble, It's use is usually wrong,

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.
