Spike Distribution Analyzer
- Indicateurs
- Version: 1.0
- Activations: 5
Spike Distribution Analyzer is a visual statistical indicator for MetaTrader 5 designed to study how spikes are distributed after sequences of trend candles. Instead of focusing on entry signals, it summarizes the structure between spikes and trend continuation in a clear visual format. The indicator can display a floating text summary, a graphic panel, or both, depending on the selected display mode.
The main purpose of the indicator is to help the trader understand how often a spike appears after a certain number of trend candles. It analyzes historical candles, identifies spike candles according to the selected threshold method, counts how many trend candles appear between valid spikes, and converts that information into a distribution. This makes it easier to evaluate whether the market is showing short spike cycles, extended trend sequences, or a mixed structure.
The indicator is built for synthetic instruments and other symbols that behave in a spike-like way. It supports Boom, Crash, and generic bull or bear spike structures. Auto detection is available for common naming patterns, and manual index selection is also included when the user wants to define the market context directly.
A practical feature of the indicator is its chart-friendly presentation. The floating text can provide a quick summary without filling the screen, while the graphic panel shows the filtered distribution in a more structured way. When a historical candle is selected through the anchor feature, the indicator can re-evaluate the minimum spike threshold from that candle. If the selected candle is not a spike but a trend candle, the panel shows “Not a spike” instead of drawing bars.
This indicator is intended as a decision-support and market-structure reading tool. It does not open trades, send orders, or perform automated trading actions. Its role is to organize statistical context in a visual form that can be read quickly during chart analysis.
How It Works
The indicator first loads historical bars from the selected symbol and timeframe. Then it calculates a spike threshold using one of three methods: preliminary mean body size, modal body size, or a fully manual points threshold. After that, it checks each candle body against the selected spike criteria and optionally applies a directional filter so the spike must also be opposite to the prevailing trend direction.
Once valid spikes are identified, the indicator counts how many trend candles appear between one spike and the next. Those counts are grouped into a frequency distribution. From that distribution, the indicator derives values such as weighted mean, mode, maximum observed k value, total groups, and related percentages. The panel can then plot the filtered bars of that distribution, while the floating text can summarize the percentage split between shorter and longer trend sequences.
What the Indicator Shows
Floating text summary
Shows a compact summary of the distribution directly on the chart. It can include the sample size, the active minimum threshold, and the percentage split between two k ranges.
Graphic panel
Shows the statistical distribution as a bar panel. Each bar represents a k value, meaning the number of trend candles found between spikes. The panel can work with absolute frequencies or percentage scale.
Anchor information
When the user selects a historical candle with the anchor, the panel subtitle reports the selected candle class, its body size, and the effective threshold used for the analysis.
Context label
If the analysis is applied to a symbol or timeframe different from the current chart, the indicator can display that external context in the visual output.
Special state for non-spike selection
If the selected anchor candle is a trend candle and not a spike, the graphic panel does not draw bars and shows the message “Not a spike”.
Practical Use
The indicator can be useful for traders who want to:
- study how often spikes appear after sequences of trend candles;
- compare short trend-to-spike cycles against longer ones;
- evaluate whether the current market structure is compressed or extended;
- review historical candles and re-check the distribution from a selected spike reference;
- keep the chart cleaner by using text mode, panel mode, or both.

Notes
This indicator is designed to organize spike statistics in a visual and structured format. It does not predict future prices and does not execute trades. It is intended to help the trader read market structure with less visual noise and with clearer statistical context.
