EHH,.... okay, how about I add a criteria... the trade must never be entered unless the minute is a multiple of 3... like 10:06 or 13:33... but never 10:02 or god forbid 14:44
You asking about something to put into an automated trading system or you talking about a "manual" applied strict rule ?
Take it for what it is worth: it's these markets near or at ATH. Wait until we are below ATH, you may see it work better for you.
Many times volume follows the move. Why wait for it? Including the PB reversal there was 4 green up bars before the volume came in.
Because it is ATH. You don't whether it is just short covering or some blow off volume. It is unknown territory so to speak, so it is hard to judge that volume. OP's method includes volume to filter his trades. All I'm saying that with the market at ATHs he shouldn't pay too much attention to it and worry what's wrong with it.
