Personally I like trading the breakout of a Flag pole however I prefer price retouching or pullback to the outer line of the flag pole and watch out for Price Action for possible price continuation something like exhaustion on a bullish or bearish candle that touched the line before pulling the trigger for a possible long or Short order with reference to the 1 hour or 2 hour timeframe definitely anot daily timeframe which I believe trading it breakout will lead to a massive drawdown if the price undergoes correction, however multi timeframe analysis is also very helpful to determine the trend of the market.
To this end I think scalpers may not have too much to do here with exhaustion, you are definitely waiting for correction and multi timeframe is useful to determine this position but I don't like to go for scalping because it is rather slow not to be caught up by retracement.. Although sometimes depending on the timeframe that this exhaustion is severe, it may change market direction especially with higher timeframe like daily above.
When you do consider you out on doing scalping then everything would really be on fastrack or would really be into that fast pacing when it comes on buying and selling or simply actively been facing up with that
volatility which is something that not all would able to pull on because i could really say that scalping is really indeed hardest thing to be done when you do make out trades. You would really be finding these
technical indicators to be that your main friend when it comes to this. The difference on here is that you wouldn't really be sticking on higher time frame on which you would be mainly focusing on smaller ones.
I have tested out on doing scalping and it turns out that it isnt really something that it is really for me. It is really that hard once you do step your foot into the market.
Lots of indicators which you might really be needing but since we do know that trading isnt an assured thing no matter how well you do make TA's then its up to you on how you would gonna handle yourself.
