Oh, no. It’s basic behavior. I’ve experienced it through every retail broker I’ve had. To avoid it, I use only limit orders, supplying them with liquidity. When you demand liquidity, you’re at the whim of their liquidity providers or others. I’ve curtailed my system/strategy to not use stop loss orders (market orders) anymore. During risk events, liquidity dries up and the retail broker is always trying to stay ahead of the spread, sometimes too much and market orders are executed.
