Do you have any noticeable trade slippage experience in your current broker or platform?
For example, I have been hit half point slippage at about 11:22am this morning when trading ES in IB's booktrader. I have placed a stop price at 1364.75, but actually executed at 1364.25. IB's support said, there were many orders hit 1364.75, .50 and .25 within a second, so my order filled at 1364.25, not at my expected price 1364.75! Wow
This is a very unusual occurence, but as you can see there was a high volume bar, which occurred at 11:23 AM this morning. This bar covers the period from 11:22:00 AM to 11:23:00 AM..There were 24,259 contracts traded during one minute, which corresponds to a total of $ 1.65 billion.
I think that you became the victim of a large instutional sell order that took out several layers of the order book at once. In such a case you may experience 2 ticks of slippage even with ES.
Just to understand how unusual this volume was: If you want to find higher 1-min bars with a higher volume than this bar, and if you exclude the contracts reported around 10:00 PM (reported block trades), then these were the only 1-min bars with a higher volume that I could find for the entire month of April.

So I guess that you were just unlucky and cannot blame the broker.

to the "stop order". From retail trader perspective, we all use some kinds of stop order to protect the our trade/acct, in a flash crash or non-crash market situation, how do we expect our stop order to be executed, in order words, how large the slippage we can accept? and more importantly how do we prevent the bad slippage in our next trading...
