Dose anyone know what the input 'slippage' means for the order in the function OrderSend()?
It is an integer, but in the MQL4 Reference, it says : "If the requested price is out of date, but present in the thread, the order will be opened at the current price and only if the current price lies within the range of price+-slippage"
Price +- slippage, that would a very big range if the slippage is an integer.
For example, if current Ask is 1.03, and slippage set as 1, that means the order will be deal within the price range(0.03-2.03). It is right?
Slippage is in points.
On most forex brokers, 10 points = 1 pip.
