Margin-9 (M9.)

What is M9.?

Margin-9 (M9.) is a professional position sizing study for Sierra Chart that automatically calculates the optimal contract quantity for each trade. The study analyzes the distance between entry price and stop-loss in real-time and adjusts the position size to maintain your predefined risk budget per trade.

Built for serious futures traders, M9. combines sophisticated position sizing calculations, intelligent multi-target contract distribution, and a dynamic risk-to-reward display into a single, powerful tool that integrates seamlessly with Sierra Chart's native order system.

Problem it Solves

Proper position sizing is one of the most critical aspects of risk management. Many traders use the same contract quantity for every trade, regardless of how far the stop-loss is from the entry. This leads to inconsistent risk: tight stops result in less risk, while wide stops expose significantly more capital than intended.

M9. solves this problem by automatically adjusting contract quantity so that the dollar risk (or percentage of account balance) remains constant for every trade.

Intelligent Position Sizing Engine

At the heart of M9. is a sophisticated position sizing engine that performs complex calculations to determine the precise number of contracts for each trade. The study considers multiple variables and executes robust mathematical operations to deliver the most accurate results possible.

Advanced Multiple Targets System

M9. features a powerful multi-target system that gives you complete control over how contracts are distributed across your take-profit levels. Each target can receive a fully customizable percentage of your total position, and the study performs intelligent rounding to ensure every contract is precisely allocated.

How It Works

• ●Per-Profile Distribution: Each of your 5 risk profiles can have its own unique TP distribution (e.g., Profile 1: "50,30,20", Profile 2: "100")
• ●Intelligent Rounding: When contracts can't be evenly divided, the study uses a smart algorithm to distribute remainders fairly across targets
• ●Limit-Aware Redistribution: If max contract limits reduce your position, the distribution is automatically recalculated to maintain your target percentages
• ●Real-Time Updates: The SIZE display in the control panel shows your current contract distribution (e.g., "[5,3,2]") at all times

Dynamic Risk-to-Reward Display

The R:R (Risk-to-Reward) display is one of M9.'s most sophisticated features. Unlike simple R:R calculators that assume equal contract distribution, this display performs weighted calculations that account for your actual contract allocation across multiple targets.

Live Adaptation

The R:R display continuously adapts to changing market conditions and order modifications:

• ●Updates when you place or modify entry orders
• ●Recalculates when stop-loss is moved
• ●Adjusts when take-profit targets are repositioned
• ●Reflects partial fills as targets are hit during the trade

Forward Reward-to-Risk (FRR)v1.3.2+

When you move your stop into profit (above entry for longs, below entry for shorts), the classic R:R ratio becomes irrelevant. M9. automatically switches to Forward Reward-to-Risk (FRR) — a metric that measures your profit potential relative to your remaining risk from the current price.

When stop moves into profit, the display automatically switches from R:R to FRR

FRR Formula

FRR = (Take Profit - Current Price) / (Current Price - Stop)

This formula calculates how much profit potential remains relative to the risk of giving back unrealized gains. A higher FRR means more upside with less risk of losing your locked-in profit.

Classic R:R (2.5R)

Displayed when stop is at risk (below entry for longs). Measures reward from entry pricerelative to initial risk amount.

Forward R:R (2.5F)

Displayed when stop is in profit. Measures remaining reward from current pricerelative to the risk of losing your locked-in profit.

FRR Color Scale

The FRR display uses a dynamic color scale to indicate trade quality at a glance:

≥ 3.0F

Excellent

≥ 2.0F

Very Good

≥ 1.5F

Good

≥ 1.0F

Acceptable

< 1.0F

Unfavorable

Trade Management Insight

An FRR below 1.0 means you're risking more (of your locked-in profit) than you stand to gain. Consider tightening your stop or taking partial profits when FRR drops significantly.

Multi-Symbol Supportv1.4.0+

Since version 1.4.0, M9. supports fully independent multi-symbol operation. Each chart runs its own M9. window with completely isolated state — including risk profiles, position data, window position, and active configuration. Trade ES, NQ, and RTY simultaneously, each with different risk setups.

Three independent M9. windows running simultaneously on ES, RTY, and NQ — each with its own risk profile and configuration

Key Benefits

Who is this For?
