A trading post-mortem and journaling web app that automatically classifies stop-outs (noise vs. structure break vs. sweep) and quantifies how alternative stop placements would have changed outcomes. Users connect their broker/export trades, and the app reconstructs the stop-out context with volatility bands, nearby liquidity levels, and time-of-day patterns to produce actionable rules like "minimum stop distance = X ATR in first 30 minutes".
A lightweight desktop/web app that normalizes fast bracket order workflows (OCO/OTO/OSO) across supported brokers and adds pre-trade checks to prevent common scalping execution failures. It provides a single “place bracket” panel, hotkeys, and latency/health monitoring so traders can detect platform instability and route orders accordingly.
A lightweight trade-journal ingestion and analytics SaaS that turns raw fills into strategy health metrics (profit factor, expectancy, max loss streak, time-of-day breakdown) automatically. It focuses on fast setup (CSV/broker export in) and opinionated, decision-oriented outputs (what to stop trading, what time windows to avoid) rather than generic charting.
