Question: What's the "deviation" option on MT5 (MetaTrader5)? How does it work?
On MT5, “Deviation” level is set to “last used”.
With this, the deviation value of the previous opened position will be automatically set in the order opening window.
“Deviation” is used to allow the platform to open position even if the market price is different from the requested price of order.
As in if a symbol price change during order creation, the price of a prepared order will differ from the market one, and the position will not be opened.
Deviation is to avoid such kind of situation by setting the parameter beforehand.
Setting up the Deviation
In order to setup the deviation parameter, please go to “Tools” → “Options” → “Trade”, then select “By Default” from the dropdown menu of Deviation, and set the numbers for it.
The maximum deviation you can set is up to 999,999,999.
