I just posted the other day about trading longer time frames and that one down fall of doing so is holding through the maintenance period . Well just had a nice gap in 6b . I had been holding because of a short signal and had not received an exit signal before the close. Just lost 2% on that one trade instead of my usual .05% per trade risk limit. Cost of doing business or should I close all open positions that I take on the 30-60 min time frame before the end of the day? The million dollar question.
