Say that the price of the AUD/USD was 0.8210. After analysing the market, you speculate that it’s on an upward trend and long a one standard lot trade at the now current price of EUR/USD 0.8250, expecting to execute at the same price of 0.8250.
The market follows the trend but goes past your execution price and up to 0.8260 very quickly – within a second. Because your expected price of 0.8250 is not available in the market, you’re offered the next best available price. For the sake of the example, that price is 0.8245. In this case, you would experience positive slippage:
0.8250 – 0.8245 = 0.0005, or +5 pips.
On the other hand, let’s say your trade was executed at 0.8255. You would then experience negative slippage:
0.8250 – 0.8255 = -0.0005, or -5 pips.
It’s important to note that slippage can occur with all types of requested orders including Stop Loss, Take Profit, Buy/Sell Stops and Buy/Sell Limit Orders. As BT Markets uses market execution, we cannot guarantee such orders.
We operate under Market Execution and for this reason, we are unable to fill a Forex order that no longer exists. If your requested price is no longer available, your order will be filled by our liquidity providers at the going market rate.
