good Questions- I have a coupla things I like to see in relation to volume.
1. the volume needs to break above the "average" volume. 2. I want to see volume increasing for several trading sessions- fuels a continued move. you do not wait that long to have entered the trade as it may be stretched thin at day 3 3. I like to see OBV going up and need both OBV and accumulation hooking up b4 I would typically enter... Out of the two, I think accumulation is the more important of the two. i wont pass if obv is going down necessarily but i will if accumulation is hooking down- its a real red flag to me.
in general, I like all of the indicators going up- ha ha!
another one that signals continuation is the slow stochs breaking the 50 line. and the MACD breaking the 0 line.
