Monitoring Prop Trading Challenge Limits and Position Size

Summary

This document describes an account dashboard for tracking five common proprietary trading challenge constraints: daily loss, maximum loss, profit target, minimum trading days, and the best-day consistency rule. It explains that loss limits can be configured as fixed or trailing, that floating profit and loss may count toward daily loss, and that the start of a trading day depends on a selected server hour. Status colors and an overall badge summarize how much room remains under each rule.

A position-sizing feature estimates the largest lot size for a proposed stop distance, using a chosen fraction of the smaller remaining loss allowance and never rounding the result upward. Presets provide typical challenge settings, while a custom setup accommodates firm-specific definitions. The document gives implementation details about reading account history and storing guard state, but provides no performance evaluation. It emphasizes that the indicator only reports risk; terminal history, timing, fees, and each firm's rule definitions can make its figures differ from the firm's dashboard.

Key ideas

• The monitor tracks daily loss, maximum loss, profit target, trading days, and best-day consistency.
• Daily and maximum loss calculations can vary with floating P&L, server-day boundaries, and trailing rules.
• Its suggested lot size uses the smaller remaining loss allowance and a configurable share of that room.
• Custom settings are needed because prop firms define challenge rules differently.
• The indicator reports limits but cannot prevent trades or guarantee agreement with a firm's figures.
