Quantitative & Institutional Trading Glossary

A rigorous trading lexicon bridges analytical telemetry with institutional execution. This glossary defines the core mathematical metrics, Smart Money Concepts (SMC), and order execution terminology utilized across the ILoveTrading platform.

1. Quantitative & Performance Telemetry

Expectancy (E)

The mathematical average payout you can anticipate per executed trade over a large sample size:

Formula / Calculation
Expectancy = (Win Rate × Average Win) - (Loss Rate × Average Loss)

R-Multiple (R)

Normalized trade performance measured as a multiple of initial dollar risk (1R):

Formula / Calculation
R = Realized Net PnL / Initial Dollar Risk

System Quality Number (SQN)

A Van Tharp statistical metric evaluating the quality, consistency, and scorability of a strategy's statistical Edge:

Formula / Calculation
SQN = √N × ( Mean(R) / StdDev(R) )

• < 1.6: Poor / Hard to trade
• 2.0 – 2.9: Good / Average edge
• 3.0 – 4.9: Excellent edge
• ≥ 5.0: Superb / Institutional quality

Sharpe Ratio

A measure of risk-adjusted excess return per unit of standard deviation (volatility):

Formula / Calculation
Sharpe Ratio = ( Portfolio Return - Risk-Free Rate ) / Portfolio Standard Deviation

Maximum Excursion Telemetry (MAE & MFE)

• Maximum Adverse Excursion (MAE): The maximum peak unrealized floating loss experienced during the trade's duration (diagnoses stop-loss efficiency).
• Maximum Favorable Excursion (MFE): The maximum peak unrealized floating profit achieved before closure (diagnoses take-profit timing).

2. Smart Money Concepts (SMC) & Order Flow

• BOS (Break of Structure): A decisive candle close beyond a major swing high/low confirming trend continuation.
• ChoCh (Change of Character): A structural break signaling an impending trend reversal.
• FVG (Fair Value Gap / Inefficiency): A 3-candle delivery sequence where candle 1 and candle 3 wicks do not overlap, leaving unfilled institutional liquidity.
• Order Block (OB): The last opposing candle prior to an aggressive institutional impulse.
• BSL / SSL (Buy-Side & Sell-Side Liquidity): Clustered resting stop orders located above swing highs or below swing lows.
• Liquidity Sweep (Raid / Hunt): A fast price surge beyond structural highs/lows designed to trigger retail stops before reversing violently.
• Inducement (IDM): A minor internal structural high/low engineered by algorithms to trap early retail entries before tapping the true Point of Interest (POI).
• OTE (Optimal Trade Entry): The institutional Fibonacci retracement golden pocket (61.8% – 78.6%) aligned with high-timeframe order flow.

3. Order Execution & Market Mechanics

• Spread: The real-time difference between the broker's Bid price and Ask price.
• Slippage: The execution price disparity between the requested order price and the actual fill price delivered by liquidity providers.
• Pip (Percentage in Point): The standard 4th-decimal unit of measurement in forex pairs (0.0001), or 2nd-decimal for JPY pairs (0.01).
• Tick: The minimum fractional price fluctuation permissible in futures and equities contracts.
