For positions established after June 12th, brokers are greatly restricted from making price adjustments to client orders. There are only 2 exceptions.
First, if a customer disputes a price, adjustments may be made, but ONLY in the customer's favor.
Second, if the broker has an exclusively straight-through processing model and the liquidity provide makes a price adjustment. In these cases, the customer must be notified within 15 minutes. Yes, that is 15 minutes from the order being executed to send a notification to the customer. Save those emails with full headers – you may need them to prove that they waited 20 minutes to notify you. If the broker isn't exclusively STP, then they don't even get 15 minutes.
"STP" stands for Straight Through Processing. IOW, no dealing desk.By the way.. what "STP" stands for?? something concerning spike-trading?
Could anyone please show me a list of all the NFA regulated brokers?
