Why does Interactive Brokers have such an enormously hard time filling market orders

These days, why does Interactive Brokers have such an enormously hard time filling MARKET orders of VERY heavily traded options in US markets? Is IBKR going rapidly downhill?

 

Why don't use limit orders that hit the bid/lift the offer?

 

Same story with limit orders. Right now SPY is at 274.28. I have reduced my limit buy to 273 as I need to leave home now but IBKR still isn't filling.

 

with six posts you are already an expert on order fills and the condition of a major trading firm.
follow your insight and short the stock.

 

Try routing orders to individual exchanges instead of using smart routing. There is a column in option trader that tells you which exchange is on the bid/ask. Right click at the column headers and configure.

 

???

If your buy limit is below the current price, how can you expect a quick fill? Or is there something I'm missing?

 

Well spotted!

 

I agree. It has been a downhill story with IBKR for me too. TOS and Tradehawk seem to have better executions.

 

I haven't noticed any execution problems with limit orders. I usually place my orders as limit inside the bid - ask spread so can't comment on market orders.

 

Ooops. I meant 275. They filled it ecentually. But it was frustratingf.
