Download script
This script is designed for the MetaTrader 4 platform to provide traders with a unique visual perspective on historical market data. Its primary function is to overlay "higher timeframe" candles onto a lower timeframe chart, allowing you to see the broader price action without constantly switching between different time periods.
How it Works
The logic operates by fetching data from a larger time interval (for example, 4-hour candles) and drawing them as distinct shapes on your current, smaller time interval chart (such as a 1-hour chart).
1. User Configuration When you load the script, you can define three main settings:
- The Target Period: You choose which larger timeframe you want to see (e.g., Daily, 4-Hour, or 1-Hour).
- The Quantity: You decide how many of these historical candles should be displayed at once.
- Color Coding: You can set specific colors for "Up" candles (bullish) and "Down" candles (bearish) to make the trend easy to read at a glance.
2. Validation Logic The script includes built-in checks to ensure the data remains accurate:
- It verifies that you have selected a standard timeframe.
- It ensures that the timeframe you are trying to view is larger than the one you are currently looking at. If you try to display a "smaller" candle on a "larger" chart, the script will provide an on-screen warning.
3. Visual Construction For every historical candle requested, the script performs the following steps:
- Data Retrieval: It identifies the exact opening time, closing time, high price, and low price for each candle of the larger timeframe.
- Drawing the Body: It creates a solid rectangle to represent the "body" of the candle (the area between the open and close prices).
- Drawing the Shadow: It calculates the midpoint of the candle's time duration and draws a thick vertical line to represent the "shadow" or "wick" (the high and low price points).
- Dynamic Coloring: The script automatically checks if the price closed higher or lower than it opened. Based on this, it applies your chosen color for either an upward or downward movement.
Summary for the User
Instead of manually clicking through different tabs to see what the 4-hour trend looks like while you are trading on a 1-hour chart, this script draws those 4-hour candles directly onto your screen. It creates a multi-layered visual history that helps you identify the "big picture" and current market momentum simultaneously.
