What is Slippage Fundedfirm is the subtle yet impactful gap between the price you click to trade at and the real execution price on FundedFirm's prop trading accounts, a core Forex market dynamic where high-speed price changes during news explosions, liquidity crunches, or volatility bursts cause orders to fill at the nearest available quote instead of your exact target, frequently nudging stop-losses or entries by 2-10 pips negatively or favorably positively, directly testing adherence to the firm's 5% daily drawdown and 10% max loss boundaries in simulated-to-funded progression.
