Psychology-Aware Position Sizing & Risk Manager
A SaaS platform that helps day traders identify their psychological comfort zone for position sizing by correlating emotional states with trade outcomes. It provides graduated scale-up recommendations based on win-rate stability and alerts traders when their position size exceeds historical comfort thresholds. The core insight comes from experienced traders reporting that account size fundamentally changes their emotional game, causing strategy breakdown even when the underlying approach is sound.
为什么这很重要
You are an experienced day trader who has noticed something counterintuitive: the larger your account grows, the worse your execution becomes. You can make consistent gains on a small account, but the moment you scale up, emotional pressure causes you to break your own rules — panic exits, revenge trades, and fear of re-entry after losses. You have tried manually scaling down to ground yourself, but there is no tool that tracks how your emotional state correlates with your trade outcomes or tells you when you are venturing outside your psychological comfort zone. You want data-driven guidance on how fast to scale up without triggering your own psychological breakdown.
- · 专为 Active day traders (options and equities) managing accounts from $500 to $250k+ who struggle with emotional discipline during position scaling and want data-driven guidance on when and how much to scale up 打造。
- · 最可能的变现方式：SaaS subscription with tiered pricing based on account size and broker integrations needed。

为什么这件事可能失败
自我反驳——最重要的信任度信号
- 1Traders under live market pressure will not consistently log their emotional state, making the core data model unreliable and the correlation insights weak
- 2Broker API integration maintenance proves more costly and fragile than expected, with breaking changes causing user churn
- 3The psychological correlation dataset per user is too small to produce statistically significant insights, leading users to perceive the tool as unscientific
证据综述
AI 如何合成此洞察——无原话引用
Multiple experienced traders across two analysis batches independently identify psychological pressure during position scaling as their primary challenge, with one describing how losing roughly 10k forced a return to single-contract sizing. Six distinct commenters mention emotional control during scaling, and the concept that account size changes the psychological game appears repeatedly. Two traders explicitly connect bankroll management principles from gambling to trading, suggesting a framework gap. Payment signals include high-capital traders comparing daily trading income to regular job earnings.
