ICT Fair Value Gap indicator on MT5 plotting bullish and bearish imbalance zones.
The ICT Fair Value Gap (FVG) MT5 Indicator is an advanced MQL5 technical tool designed for MetaTrader 5. It automatically scans the market for 3-candle imbalances, plots Consequent Encroachment levels, and sends push alerts upon void mitigation.
ICT Fair Value Gap (FVG) MT5 Indicator Overview
High-Speed Fair Value Gap Detection on MetaTrader 5
The Fair Value Gap (FVG) MT5 Indicator utilizes the native 64-bit multi-threaded architecture of MetaTrader 5 to scan multi-pair, multi-timeframe price series for liquidity voids. In institutional Smart Money analysis, an FVG represents a 3-candlestick market imbalance where aggressive volume displaced price rapidly, leaving one side of the auction book unfilled.
Because institutional algorithms actively rebalance inefficient order flow, price frequently retraces into these open voids. The MT5 indicator automatically plots Bullish (BISI) and Bearish (SIBI) imbalance boxes, projects 50% Consequent Encroachment (C.E.) reaction lines, and delivers instantaneous mobile push notifications when price penetrates unmitigated gaps.
BISI vs SIBI Imbalance Classifications
FVG patterns are divided into two primary structural forms depending on market direction and liquidity delivery:
Buyside Imbalance Sellside Inefficiency (BISI)
Forms during an explosive upward candle where buying volume dominates. The void between Candle 1 High and Candle 3 Low acts as fresh institutional demand support on pullbacks.
Sellside Imbalance Buyside Inefficiency (SIBI)
Forms during an aggressive downward candle where selling volume dominates. The void between Candle 1 Low and Candle 3 High acts as fresh institutional supply resistance on retracements.
Advanced Inversion FVGs (IFVG) & Balanced Price Ranges
Inversion Fair Value Gap (IFVG)
When an FVG is cleanly broken through by a closing candle, the former support level flips into a high-conviction resistance barrier (or vice versa).
Balanced Price Range (BPR)
Created when an upward BISI is immediately engulfed by a downward SIBI, highlighting an institutional fair value equilibrium pivot.
Consequent Encroachment (50% C.E.) & Invalidation Rules
In Smart Money trading, the 50% midpoint of an FVG box is termed Consequent Encroachment (C.E.). If price respects the C.E. level with long rejection wicks, the underlying institutional trend remains exceptionally strong. If price completely closes beyond the opposite boundary of the FVG, the imbalance is deemed invalidated and flips into an Inversion FVG (IFVG).
MQL5 Native High-Performance Architecture
- 64-Bit Multi-Threading: Renders hundreds of historical imbalance boxes across all 21 MT5 timeframes without CPU bottlenecks.
- Tick-Level Mitigation Verification: Evaluates tick stream data in real time to immediately remove or gray-out mitigated boxes.
- Direct Push Alert System: Sends instant push notifications with symbol, timeframe, and gap coordinates to the MT5 mobile app.
Pro Trader Guidelines for Trading FVGs on MT5
- Filter for Higher Timeframe Confluence: Prioritize 15-minute or 1-hour FVGs that form inside Daily or 4-Hour Order Blocks.
- Monitor Session Openings: Look for displacement FVGs formed immediately after London Open (08:00 GMT) or New York Open (13:00 GMT).
- Utilize Consequent Encroachment for Entry: Entering at the 50% C.E. level allows for tighter stop losses and improved 1:4+ risk-to-reward ratios.

Trading Strategy & Entry Rules
Step 1: Multi-Timeframe Bias
Establish directional bias on H4/Daily using market structure breaks (BOS).
Step 2: Identify Inefficiency Voids
Locate prominent unmitigated Fair Value Gaps left behind by momentum displacement.
Step 3: Wait for 50% Equilibrium Fill
Watch for price to pull back cleanly into the 50% Consequent Encroachment (C.E.) zone.
Step 4: Lower Timeframe Execution
On M5, trigger entry on confirmed rejection patterns or Change of Character (CHoCH) with defined stop-loss limits.

}How to Install & Compile in MetaTrader MT5
Follow this complete step-by-step technical guide to install, compile, and configure the custom MQL5 indicator on your desktop trading terminal:
Download Source File
Download the raw .mq5 source file to your computer using the direct download button below.
Open MT5 Data Folder
Open your MetaTrader terminal, navigate to the top menu bar, click File → Open Data Folder, and open the MQL5 → Indicators subfolder.

Integrating with Expert Advisors (EA) via iCustom()
Algorithmic traders and quant developers can seamlessly integrate this indicator into custom automated Expert Advisors (EAs). Because the indicator calculates values into standardized plot buffers on closed bars, you can query buffer values using native MQL5 functions without recompilation:
// MT5 MQL5 iCustom Calling Syntax Example
int indicatorHandle = iCustom(_Symbol, _Period, "FairValueGap_FVG_MT5");
double buyBuffer[1], sellBuffer[1];
CopyBuffer(indicatorHandle, 0, 1, 1, buyBuffer);
CopyBuffer(indicatorHandle, 1, 1, 1, sellBuffer);
if (buyBuffer[0] != 0.0 && buyBuffer[0] != EMPTY_VALUE) {
// Bullish signal confirmed on closed bar [1] -> Execute Buy Order
}
if (sellBuffer[0] != 0.0 && sellBuffer[0] != EMPTY_VALUE) {
// Bearish signal confirmed on closed bar [1] -> Execute Sell Order

Institutional Risk Management & Capital Preservation Protocol
Professional proprietary trading desks operate under strict risk control parameters to ensure longevity:
- Maximum 1% - 2% Risk Rule: Never risk more than 1% to 2% of total account equity on any individual trade setup.
- Minimum 1:2.5 Risk-to-Reward Ratio (RRR): Only execute setups where the potential profit target is at least 2.5 times greater than the stop-loss invalidation distance.
- Multi-Timeframe Confluence Required: Never take an intraday trade against the primary Daily or 4-Hour trend direction.
- High-Impact Economic News Awareness: Avoid entering new positions 15 minutes before and after major macroeconomic data releases (such as US Non-Farm Payrolls, CPI Inflation, and central bank FOMC/ECB interest rate announcements).
Strategy Backtesting & Historical Modeling Protocol
Before deploying any indicator or automated strategy in a live trading environment, professional quants conduct rigorous multi-year backtesting across varying market conditions:
- 99.9% Tick Data Modeling: Use high-precision tick history from reputable data providers (such as Dukascopy or TrueFX) to eliminate spread anomalies and slippage distortion.
- Spread & Commission Inclusion: Always test with realistic variable spreads and broker commission structures to simulate true real-world execution friction.
- Out-of-Sample Walk-Forward Optimization: Avoid curve-fitting by validating parameters on 70% in-sample data and testing robustness on 30% out-of-sample data.
- Monte Carlo Drawdown Analysis: Run randomized trade sequence simulations to calculate the maximum potential drawdown under adverse market volatility regimes.
Virtual Private Server (VPS) & Execution Latency Optimization
For active day traders, scalpers, and automated Expert Advisors, execution speed is paramount:
- Low-Latency Proximity Hosting: Deploy your MetaTrader MT5 terminal on a dedicated Windows VPS located in the same financial data center (e.g. Equinix LD4 in London or NY4 in New York) as your broker server to achieve sub-millisecond execution times.
- Terminal Memory Optimization: Go to Tools → Options → Charts and decrease Max bars in chart to 5,000 to conserve CPU and RAM resources.
- Audio & News Feed Disabling: Turn off unneeded terminal audio event chimes and background news feeds to ensure 100% of CPU cycles are dedicated to indicator calculations.
