Re: Bad ticks

Unless I am mistaken, a buy limit order placed above the market on Globex
will be executed by Globex at the current market price.  That is in fact how
Globex brokers simulate a market order on Globex, which has no native
support for market orders.  The broker takes your market buy and puts it on
Globex as a limit buy order 10 points (for ES) above the market.

This is one reason why ES has so few "bad ticks".  Human error of this kind
results in a market order, not a whacked out fill way off from the current
market.

Stocks are a different animal of course...
