Check out the new article: From Novice to Expert: Creating an MTF CRT Overlay Indicator in MQL5.

Higher-timeframe CRT ranges are informative, yet traders often execute on lower timeframes without that context. We implement an MQL5 indicator that reads higher-timeframe OHLC, projects the full candle range, body, and wicks onto the active lower-timeframe chart, and marks entries, stops, and targets. This improves situational awareness and removes the need to switch windows.

Traders who use Candle Range Theory (CRT) face a practical gap: structural levels visible on higher timeframes (H1, H4, Daily) disappear when they drop to execution timeframes (M1–M30). That loss of context leads to misreads—what looks like a breakout on a 5‑minute chart is often an institutional liquidity sweep on the daily chart. Any practical solution must therefore be precise and testable: each lower‑timeframe bar must be unambiguously mapped to its parent higher‑timeframe candle (time‑accurate anchoring), the overlay must not repaint (signals fixed only after the HTF candle closes), and the tool must display the HTF candle's full range, body and wicks directly on the execution chart without manual drawing or window switching.

This article presents an MQL5 implementation that meets these requirements: it projects HTF OHLC onto the current chart, ties every LTF bar to its HTF parent, and confirms CRT patterns only at HTF close—turning CRT from a memory task into a reproducible, execution‑ready overlay.
