Reconstructing Tick-Based VWAP and Order-Flow Imbalance Signals
Summary
The article describes an on-chart MetaTrader 5 tool that estimates selected market-microstructure signals from broker-provided ticks when full depth-of-market data is unavailable. It combines a tick-derived VWAP reference, directional tick-volume imbalance, rolling signed-volume flow, and spread monitoring. The tool can display alerts and markers, add slippage assumptions to risk and position sizing, and use ATR-based stops as part of its sizing logic.
The article explains how to interpret price relative to VWAP, positive or negative imbalance and flow, and wider spreads as potential signs of higher execution costs. It presents the tool as a proxy for order-book insight, not a direct view of resting liquidity: upticks and downticks stand in for buying and selling pressure, and VWAP is reconstructed from trades or midpoints. It gives no performance evidence in the supplied text, recommends validating signals on replay or demo data, and emphasizes that settings need instrument-specific tuning.
Key ideas
- The tool estimates VWAP, directional imbalance, rolling flow, and spread conditions from incoming ticks.
- Price above or below the tick-derived VWAP is used as a reference for relative strength or weakness.
- Upticks and downticks are proxies for buying and selling pressure, not direct measurements of order-book depth.
- Signal thresholds and windows should be adapted to each instrument’s tick rate and volatility.
- The article recommends validating signals and sizing rules with replay or forward data before automating trades.
