I saw those sudden volume spikes, but it also just started trading and emotion always comes. Just not enough time involved yet IMO
Listen to your own experience. If you've had luck with these, repeat what ever you did before. But try to find something in the chart or TA which caused you to act. And call that a pattern after it works at least 3 times. This is how you accumulate personal Tips, rules, and rules of thumb. Noticing what works for your trading style and repeating it, when you have seen it happen enough.
Then pass it on to others!
