Sub Scaler
This is a powerful addition to your MetaTrader 5 toolkit designed to optimize market analysis and performance. This technical indicator acts as a specialized analysis tool designed to visualize market data. It helps traders identify emerging trends, momentum shifts, and key support or resistance levels by plotting statistical calculations directly onto price charts.
How to Setup and Use Sub Scaler
1. Installation: Place your file in the MQL/Indicators folder via "Open Data Folder" and restart your terminal.
2. Loading: Find the indicator in the Navigator, drag it onto your chart, and configure the input parameters in the popup window.
3. Customization: Press Ctrl+I to open the indicator list, select your tool, and click "Properties" to change colors, levels, or visual styles.
4. Updating: Replace the old file in the Indicators folder with the new version and restart the platform to apply changes.
Frequently Asked Questions
Q: Why is my indicator not showing? A: Verify the file is in the MQL/Indicators folder, or try right-clicking the "Indicators" tree in the Navigator and clicking "Refresh."
Q: Do custom indicators slow down the platform? A: Too many complex indicators can impact performance; remove unused ones via the "Indicator List" (Ctrl+I).
Q: Can I use MT4 indicators on MT5? A: No, MQL4 and MQL5 are distinct languages; ensure the indicator is compiled specifically for your platform version.
Description & Settings
This is a helper indicator which allows you to adjust vertical scale of a subwindow interactively (using keys), which is useful for zooming in and zooming out graphs of your favourite indicator placed in the same subwindow.
SubScaler allows you to view graphs with larger level of detail, when some enormous candles force the terminal to squeeze the overall picture along the vertical axis. This is a rare problem, but if it occurs, MetaTrader does not provide a built-in mechanism to zoom in/out ad hoc.
SubScaler does not have buffers and displays nothing on its own.
SubScaler must be the 1-st indicator in the subwindow, that is it's added to the main window and initiates new subwindow creation. Your indicator (whose scale should be controlled by SubScaler) must be the next one, that is it's dropped to the empty subwindow with SubScaler.
It's required to enable 'Inherit scale' option for your indicator!
The example above demonstrates the option for standard Volumes indicator, but it works in the same way for others, including custom indicators.
When both indicators are applied to a subwindow, use Up/Down arrow keys to scale up/down; hold Shift with the arrow keys to move up/down.
Scaling up means that picture becomes larger (zoom in, can be clipped), whereas scaling down means that picture becomes smaller (zoom out).
The chart must have keyboard focus for the keys to take effect.
Input parameters
Initial Maximum - upper bound of the data range at primary placement on a chart, +1000 by default;
Initial Minimum - lower bound of the data range at primary placement on a chart , -1000 by default;
Scale Factor - the step for the scale increase/decrease [0.01 ... 0.5], 0.1 by default;
When a chart is restored at the terminal start-up or from a loaded template, the SubScaler picks up the scale from the previous state.
