Mediana Trendline - indicator for MetaTrader 5

Mediana & Parallel Lines Multi-Timeframe (MTF Channel)

Description

Mediana & Parallel Lines MTF is a visual indicator for MetaTrader 5 that draws parallel channels directly on the current chart, based on the last two closed candles of higher timeframes (Monthly, Weekly, Daily, H4, H1, M30, M15).

Each channel consists of 3 parallel trend lines:

• Median Line – drawn through the midpoint (Open+Close)/2 of the last two closed candles of the selected timeframe;
• High Line – parallel to the median, starting from the High of the second-to-last candle;
• Low Line – parallel to the median, starting from the Low of the second-to-last candle.

The slope of all three lines is identical, calculated from the change in the median between the two reference candles. This provides a simple, clear visual projection of the direction/trend of that timeframe, automatically extended into the future (ray right).

Key Features

• Supports 7 timeframes simultaneously: MN1, W1, D1, H4, H1, M30, M15 — each can be enabled/disabled independently.
• Individual color for each timeframe, fully configurable from inputs.
• Configurable line width and style (LineWidth, LineStyle), applied globally.
• Automatic safety rule: a timeframe's channel is only displayed if that timeframe is higher than the current chart timeframe (e.g. the Daily channel won't appear if you're already viewing the D1 chart or higher) — prevents irrelevant/redundant data from being shown.
• Performance optimized: calculation logic runs only once per new bar (not on every tick), allowing smooth operation across dozens of charts simultaneously without lag.
• Auto-cleanup: all graphical objects are automatically deleted when the indicator is removed from the chart ( OnDeinit ).
• Info panel: displays a list of currently active channels in the chart corner (via Comment ).
• No repaint — relies exclusively on already closed candles (index 1 and 2).

3. Customize colors and line style as preferred.
4. Channels update automatically whenever a new candle forms on the current chart.

Recommendations

Useful for traders applying multi-timeframe top-down analysis, providing a quick visual representation of the direction and magnitude of price movement on higher timeframes, overlaid directly on the execution chart.
