The easiest way to do it is with the "Momentum" indicator.
FSB Pro comes with two versions of Momentum:
- "Momentum" - it calculates the difference of the current Close with the Close "n" bars back: Price(t) - Price (t-n). It may optionally apply MA smoothing.
- "Momentum MT" - this is the MetaTrader interpretation. It calculates the momentum as Price(t) / Price (t-n)
The first version is more useful to you.
In this example, we detect a minimum price range for 5 bars. Level 0.0100 means that we will have a signal when the range is greater than 100 Pips.
