Why has my pending order been executed or Stop loss/take profit triggered when the price has not reached the specified price?

As an illustration, if you started a sell position on EURUSD at 0.99700 and set a stop loss of 1.00, your stop loss will be activated when the Ask price reaches 1.00. As a result, if the spread at the time is 1 pip, your order might have been closed while the price on the chart was merely 0.0999.

By default, the price charts show BID prices. If the current ASK price is not shown on your platform, you can add it by right-clicking on “Market Watch” and then selecting “Spread Option.”
