Like I said, you have to know the instrument.
If you know the fluctuation size, you know which way is the market headed.
Crimson vertical lines: downtrend / downtrend reinforced
Blue vertical lines: uptrend / uptrend reinforced
I know what you are going to ask: where to get in on i.e. the uptrend when there is not a touch on the plotted lines all the way to its end?!
The reality is that you can get in anywhere. The optimal spots are the continuation stochastic divergences, the RSI2 deeply oversold points and as close as you can get to your green lines – with the stop loss below the powder blue.
It goes without saying, EUR/USD, 30 min. Only.
