Ok, what is the “probability” of an intraday trend continuation? Any figures? For example when an index is up 1.5% or 2%.
I don't have exact stats. But it isn't like up 1.5% ah-ha! now we have probability of an uptrend

. It's not that simple there's multiple factors and things I use.
Example:
#1 It matter where the move originated from
#2 It matters what higher time frames are doing (recently regained or lost)
#3 Positioning of EMA's also adds probability
#4 When did the move start getting overbought
#5 How extensive was the down move, prior to regaining? If it's massive and we regain it increases chances of an opposing extended move in opposite direction as people were trapped and positioned incorrectly.
Just know when all the factors align I know a full reversal is unlikely and that any shorts I do take if I take any, that it's unlikely they produce as well.
Again it isn't an all or nothing thing. There's various levels and degrees on the move. Not every trend day is un shortable or unbuyable.
Just the way I do it and my thoughts.
