Minimizing Slippage
Slippage refers to an order being filled with a different price than that which was streamed by the price feed at the time of order request (or with a different price than requested when a limit order or stop is used). This can occur naturally when trades are either opened or closed using market or limit orders. It can be both positive (better price than expected) or negative (worse price than expected) and the split in this regard should be roughly 50/50. The two forms of natural slippage and why they occur are as follows:
- Latency based slippage – Occurs in volatile markets as the price moves between the time of order request and the time an order is filled.
- Volume based slippage – Occurs when an order is larger that the available top-of-book (level 1) price, so any overflow is filled at the next best pricing level(s) and the order is filled using a VWAP (volume weighted average price).
ABF Trade does its very best to ensure slippage either does not occur or is kept to a minimum by following certain measures. These include using infrastructure that reduces order latency, matching trades on its own book whenever possible, and carefully selecting external liquidity venues with the best pricing at the deepest pricing levels available.
