My no-trade calendar
Some days I just don't run it. Not because the strategy can't handle them, but because I can't evaluate the results afterwards — too much of the move is about one event rather than the thing I'm trying to trade.
On my list: FOMC days, the session before a long holiday weekend, and any day I'm traveling. Earnings for names in my universe get the symbol excluded rather than the whole day.
Half-days are the sneaky one. Thin, weird, and they'll happily produce a result that means nothing.
