Understanding Slippage and the Consequences of Unfair Execution
- Brokers can unfairly insert execution delays on several order requests, creating massive slippage.

Clients (mainly traders and asset managers of derivatives brokerages) invest significant time to develop and deploy strategies that will hopefully generate profit. A derivatives broker is expected to execute client trades in the best interest of their clients, which includes not trading against their clients.
Not only is this professional behavior, but it is also a legal requirement of MiFID 1/2 and equivalent laws that outline how brokers should handle their fiduciary responsibility to their clients.

Slippage is a very contentious issue among retail traders, which can lead to issues. Many traders view levels of slippage at brokers as a key determinant for their business. For example, in forex trading, if a trader places a trade intending to enter a buy on the EUR/USD at 1.1080, but they only get into the market at a price In financial trading, slippage refers to the difference in price between the price an order was intended or expected to be filled and the actual price an order was filled.

- Causing asymmetric or artificial order delays between different clients or different accounts without a specific reason (technically bait and switch, but also related to asymmetric slippage).
Lets watch and see what happens when an offending broker intentionally delays orders.
When a broker trades against their client’s instructions, it does more than cause a client to potentially generate [greater than usual] losses. The losses can then have a domino effect in causing either clients and/or other stakeholders (hedge fund, private equity, pension funds, allocators, etc) to lose confidence in the trader/asset manager. The trader could be blamed or the track record that took months or years to build is irrevocably tarnished.
Perhaps for some brokers, STP has another meaning: Straight To Pocket.
