High precision tick spread monitor with real time Max and Avg curves for MT4 and MT5. - MetaTrader 5용 지표

Spread is one of the most critical execution friction points in modern retail trading, particularly for scalpers, algorithmic systems, and news traders. While standard MetaTrader terminal charts only reflect the single-point snapshot spread at the current millisecond, true market conditions fluctuate significantly across each candle. Substantial spread widenings during daily server rollovers (swap time), session transitions, and high-impact economic news releases are completely invisible on standard price charts.

The Spread Monitor indicator is an analytical subwindow diagnostic tool designed for both MetaTrader 4 and MetaTrader 5. It continuously tracks incoming live ticks and draws two distinctive statistical curves per bar: the Maximum Spread reached within that period, and the Average Spread across all captured ticks. This empirical data helps traders verify true broker execution quality and properly calibrate risk parameters.

Underlying Concepts and Interpretation

• Max Spread Curve (Tomato Line): Pinpoints the peak spread spike within each candlestick. This metric is essential for algorithmic traders to set realistic Max Spread Allowed protection filters on automated EAs, preventing orders from triggering during liquidity gaps.
• Avg Spread Curve (Dodger Blue Line): Represents the true volume-weighted mean spread over the duration of the bar. It gives manual scalpers and day traders an objective benchmark of their actual transaction cost.
• Live Subwindow Dashboard: Displays current live spread, active bar average, active bar maximum, and recorded tick count in real time in the top-left corner of the indicator window.

Recommended Symbols and Timeframes

This indicator is universal and can be attached to any financial instrument, including Forex currency pairs (EURUSD, GBPUSD, USDJPY), Gold (XAUUSD), equity indices, and crypto CFDs. It is most informative on lower timeframes such as M1, M5, and M15, where intra-bar spread widening is most prominent during session rollovers and macroeconomic releases.

Description of Input Parameters

All external parameters are documented below to allow convenient configuration directly from the Inputs dialog:

Note: On MetaTrader 4, legacy history files do not record historical tick spreads, so the indicator records live ticks while connected. On MetaTrader 5, the indicator leverages native local tick storage to accurately reconstruct past bar spreads immediately upon loading.
