Hello all,
After about 2 years of option trading now I have come to see a very common occurrence. I will often put in a limit option order for around the current price. Buys at bid and sells at ask, therefore not triggering immediately and less fees.
It seems that almost EVERY time I get a fill, the BID/ASK immediately end up well out of the opposite way. When I buy, price goes down. Sell, price goes up.
For example. I had a sell order in at 0.15 with the bid/ask at 0.14/0.15 for about 10 minutes today. This option consistently has no more than a 1 cent spread. Immediately, and I mean it, after my fill the bid/ask jumped to 16/17. This happens all the time.
Is it coincidence? Am I not fully informed? Are the prices being manipulated between the exchange and my screen to make a profit for IB?
Thanks for any input.
