BuffersHunter

BuffersHunter is a script that reads and analyzes buffers of any MetaTrader 5 indicator. No more guessing which buffer holds buy signals, where the levels are, and which buffers contain indicator lines. Run the script — and in a second you get the complete structure of all buffers with auto-detection of their types.

Who is this script for?

For EA developers. You found an interesting indicator and want to use its signals in your robot, but you don't know the buffer numbers or what they contain. BuffersHunter shows everything in one run.

For trader-researchers. You are studying a new indicator and want to understand what data it transmits. There may be hidden buffers with useful information that you don't see on the chart.

For those who buy indicators on the Market. Not all developers document the buffer structure. BuffersHunter helps you figure it out yourself.

How it works?

1. Select the folder (Market, Examples, Indicators) and name of the indicator — exactly as in the Navigator

2. Run the script on any chart

3. The result appears in the journal and is saved to a text file in the  MQL5\Files  folder

The script connects to the indicator with default settings, reads a specified number of bars, and analyzes the contents of each buffer.

Important: You don't need to attach the indicator to the chart to read its buffers — the script reads everything directly: attaches the indicator, reads the buffers, and detaches the indicator.

What does the script show?

For each buffer it outputs:

• Buffer type — auto-detected based on value analysis

• Fill rate — what percentage of bars contain values

• Max continuous — longest uninterrupted run of non-zero values

• Current value at bar zero

• History of the last N bars (configurable)

• Last non-zero value — if the visible history is all zeros

Buffer types detected by the script:

Example output

After such analysis it's immediately clear:

• Buffers 16-25 — indicator lines (prices, levels)

• Buffer 11 — confidence filter (values 0.50)

• Buffer 26 — BUY/SELL signals (1 and -1)

• Buffers 4-6, 12-15 — unused

Important notes (honest and transparent)

1. Auto-detection is approximate

The script analyzes the last N bars (default 100) and makes a conclusion about the buffer type based on statistics. This is an assumption, not an exact fact. Some indicators may use buffers in non-standard ways. Always verify on the chart.

2. Indicator runs with default settings

The script does not pass parameters to the indicator. If the indicator requires mandatory parameters at startup — the script cannot read it. In this case you will see an error.

3. Unused and disabled buffers

Zero buffers may be unused or may be disabled in the indicator settings. The script cannot read values from buffers of parameters disabled by default — they remain UNKNOWN. Increase  Bars to search  (e.g., to 500 or 1000) — the signals may simply be very rare.

4. Time in buffers

Some indicators store signal time (Unix timestamp) directly in the buffer. The script detects such values and displays them in a readable format.

How to use results in an EA?

Once you've identified the buffer numbers, using them in code is very simple:

// Connect to indicator
int handle = iCustom(_Symbol, _Period, "Market\\IndicatorName");

// Read signal buffer
double signal[];
CopyBuffer(handle, 26, 0, 1, signal);

if(signal[0] == 1.0)
    OpenBuy();
else if(signal[0] == -1.0)
    OpenSell();
