The KCI-Directional Matrix (KCI-DX) is an advanced, physics-inspired analytical tool that extracts market kinematics by measuring price path length and volatility energy. Unlike conventional momentum tools, KCI-DX employs a dynamic Z-Score normalization combined with a Sigmoid activation function. This ensures the output is flawlessly bounded between 0 and 100, providing hyper-responsive trend strength identification and directional bias without distortion from historical extremes.

The script retrieves your broker’s actual spread from the ‘spread’ field of the M1 bars and displays the median, the 90th and 99th percentiles in price units, in pips and as a percentage of ATR, and also exports the average and maximum spreads for each hour of the day to a CSV file. This is needed to test strategies against the actual costs on your account, rather than against a ‘typical’ spread estimated from memory.

The SMC Order Block Detector indicator features an Advanced Smart Money Concepts (SMC) Order Block (OB) Engine inspired by the TradingHub 3.0 methodology. It is specifically engineered to automatically detect, track, and manage institutional Order Blocks with high precision on MetaTrader 5. A key highlight of this indicator is its Smart Overlap Management: when new Order Blocks form and overlap with existing active zones, the algorithm intelligently evaluates their Fair Value Gap (FVG) sizes. It automatically filters out and deactivates weaker or redundant zones, ensuring that only the highest-probability institutional levels remain on your chart.

Builds a rolling, volatility-adaptive volume profile over a configurable lookback window and plots the Point of Control (POC), Value Area High/Low, and statistically significant High/Low Volume Nodes (HVN/LVN) directly on the chart.

A free, read-only MetaTrader 5 panel that converts your prop firm's daily reset rule (written in whatever time zone the firm uses) into your broker's actual server time, shows a live countdown to the next reset, and warns you before a daylight-saving shift moves the boundary by an hour. Sends no orders, reads no account data, display only.

The Auto ZigZag Fibonacci Golden Zone indicator automatically detects the latest swing high and low, draws key Fibonacci retracement levels (50%, 61.8%, 78.6%), and highlights the Golden Zone between 61.8% and 78.6% as an optimal pullback entry area. The indicator includes a real-time dashboard, optional buy/sell signals, and full color customization. Works on all symbols and timeframes. Always test on a demo account before live trading.

Builds a horizontal volume histogram over a recent lookback window and marks the Point of Control and Value Area using the standard TPO/volume value-area expansion algorithm — not just POC ± a fixed offset. Refreshed once per new bar, drawn as a sidebar next to price.

Adaptive MACD is a dynamic momentum indicator that adjusts its smoothing based on market conditions. It calculates a Pearson correlation coefficient between price and bar index over a user-defined period, then uses the resulting R² to blend two different MACD coefficient sets. This makes the MACD line more responsive during strong trends and smoother in sideways markets. The indicator plots a color-coded histogram (strong/weak bullish/bearish) and an optional auto-contrast MACD line that adapts to the chart background. Inputs allow customization of the R² period, fast/slow lengths, signal period, and colors. Suitable for trend-following and detecting momentum shifts.
