    Indicator Overview

    This indicator is designed to provide traders with a visual panel on the chart, where they can enter their desired trade size, view the calculated risk percentage, and execute Buy or Sell trades instantly. It automates the risk calculation process, reducing errors and ensuring that trades are aligned with proper money management principles.

     

    Background & History

    Position sizing and risk management are fundamental concepts in trading. Many traders lose money not because of a poor strategy, but because they trade with inconsistent or excessive risk. This panel was designed to simplify the process by combining lot size input, real-time risk calculation, and quick order execution into a single, compact interface. It brings together long-established risk management practices with modern cTrader UI features.

    How the Indicator Works

    The panel analyses user input (lot size or volume), the symbol’s pip value, and the account equity. It assumes a default stop loss distance in pips and calculates the monetary and percentage risk of the trade. The results are displayed instantly on the chart as “Risk per trade: X%.” The trader can then click "Buy" or "Sell" to place an order with that risk profile. The panel also adapts its position according to user preferences, allowing flexibility in chart layout.

     

    Key Features

    The indicator provides a clear and functional interface to simplify position sizing and trade execution.

    • Real-time risk calculation based on lot size or volume.

    • Adjustable panel position (top/bottom, left/right).

    • Integrated Buy and Sell buttons for instant execution.

    • Displays risk as a percentage of account equity.

    • Clean, compact design suitable for all chart types.

     

    How to Use it for Trading

    Traders can use the panel to enforce disciplined risk management.

    • Select input mode (lot size or volume).

    • Enter trade size into the input field.

    • Review the displayed “Risk per trade” percentage.

    • If acceptable, click Buy or Sell to place the trade instantly.

    • Combine with trend analysis to align risk with market direction.

    • Beginners should start with small lot sizes and focus on keeping risk below 1-2% of account equity per trade.

     

    Inputs & Parameters

    This indicator allows customisation through the following parameters.

    Parameter Default/Type Description
    Input Mode LotSize Choose whether to enter trade size as lot size or as volume in units.
    Panel Position BottomRight Select the location of the risk calculator panel on the chart.

     

    The risk percentage is calculated using account equity, lot size (or volume), pip value, and a default stop loss distance.

    The formula is:

    Risk % = ((StopLossPips × Volume × PipValue) ÷ AccountEquity) × 100

     

    Advantages

    This panel helps traders standardize their risk per trade and avoid emotional or inconsistent position sizing. It reduces calculation errors and speeds up execution. The on-chart interface is intuitive, keeping risk management transparent at all times.

     

    Disadvantages

    The default stop loss distance is fixed in the code, which may not reflect every trader’s strategy. Traders must adjust their stop levels manually after trade execution if they differ from the preset value.
