Volume at key areas

One thing I've been really focused on the last two days - almost like I rediscovered this - is the relationship between price and volume at key areas of support or resistance. Say I'm in a trade and I enter short above the OR low, which I often do, and price moves towards the OR low and I start seeing some weakness. Sometimes my reaction is 'Get the f out... the sky is falling... abort, abort, abort!!!" However, now I look to see if there's an increase in volume at the key area (say the OR low) and if there's a bullish candle that forms soon afterwards. The screenshot below of ADSK from yesterday shows a good example of what I'm talking about:

• Red arrow shows increase in volume at the OR low
• The candles following this increase are not bullish and that's a signal for me to stay with the trade until I get a bullish formation
• Price continues to drop downward, hit the fib. ext where I sell and realize I fumbled as price dropped even further

Here is a short from the other day (AA) where price fell to the OR low, volume increased and a bullish candle formed afterward. I did get out... and save myself a lot of losses. I probably should've reversed my position at that point.

• Red arrow shows increase in volume near OR low (support)
• Very bullish candle formed afterwards which was above the 5ema and then price took out that high
