What is Historical Price Projection?
Historical Price Projection is an MT4 indicator that compares the current price sequence with historical price movement and extends a teal projected path into the chart's right-hand side, surrounded by a gray area.
A vertical execution-window line marks where the comparison begins, keeping the projected path intended as a visual comparison with the candles that subsequently form, rather than as a fixed forecast, alongside the current chart view.
How to use Historical Price Projection
Read the projection together with the candles that form after the marked starting point:
Where it helps
The vertical execution-window line marks the starting point for the displayed comparison, the projected line and its surrounding area have independent display settings, and Max Bars to Use controls how much chart history is considered.
