Time of trade

When you have a trading system you are placing on this site, how long does it take for market trades to get filled? I’m talking about high volume stokes and options, not ones with little or no volume. Please let me know.


Market orders should be filled nearly instantaneously. If you experience a problem, please let me know. -MK

I had entered a market sell order to be executed at today’s open. The order did not execute until 9:43 a.m. I think this would be considered a problem.
