- Walk the Line
There are a handful of assets for which pronounced trend movements can often be observed, for example, currency pairs including JPY. For such assets, it is possible to use a signal called "Walk the Bollinger Line."
If there is a pronounced upward trend on the chart and the Inversion Bollinger is fluctuating around the +2σ level, then you may open short-term up trades.
Conversely, if the chart shows a downward trend and the indicator reads around the -2σ level, you may open positions in the direction of the trend, downwards.
