What is Echo Forecast?

Echo Forecast is an MT4 indicator that compares a selected evaluation window with similar historical price movement. It highlights evaluation, correlation, and reference areas, then displays a blue reference path for comparing the current chart with the selected historical example.
The path is a historical comparison rather than a future price projection. Use it as a visual reference alongside current price behavior, support and resistance, and broader chart context.
How to use Echo Forecast

Compare the blue historical reference path with the evaluation, correlation, and reference areas:
- Locate the blue path to see the displayed path based on a similar historical movement, not a fixed future result.
- Use the gray evaluation area, teal correlation area, and orange reference area to identify the compared sections.
- Adjust Evaluation Window, Forecast Window, Forecast Mode, Source, and area colors to make the comparison legible.
- Note where the current movement resembles or diverges from the historical example while keeping the surrounding chart context in view.
Where it helps
Historical matching can shorten manual chart comparison, colored areas distinguish the reviewed segments, and the reference path adds context without requiring a separate chart study.
