In case of high volatility after the release of important news or poor internet connection, requote is possible (cancellation of the order execution and an offer of a new price), as the price has significantly changed while the request was passing from the client’s terminal to the company’s server.
To avoid a requote when creating an order you need to set maximum allowed deviation – the allowed deviation from the requested order price.
When setting a deviation the order will be executed at the current price, if the difference between the requested and current prices is less than the set deviation.
In NetTradeX platform the deviation is set in pips in the Make deal window.
In MetaTrader 4 platform the deviation is set in the same window as well.
