Thank you @ADESAN01 that makes sense and helps to explain the situation and I will try to bear that in mind as I go forward. It is a shame I am in the UK as it only gives me a couple of hours to trade after the day job in the dailies. I am looking at overnight IC trades to help with that but my heart is as a scalper.so I just need to adjust my thinking a little as the spread I chose was because of the low risk and potential move to the ceiling being a more likely move, but had not considered how proximity might affect the liquidity - a good learn so thanks again
