트레이딩 기록 자동화 어떻게 하고 계신가요? 🤖

Good questions. I spent a few years building FX trading infrastructure at a bank and now I'm building a desktop app in the same space, so I've gone through a lot of this.

**On the metric question:** The thing I always wanted but couldn't get from a spreadsheet was strategy-level attribution. Not just "I made $X on EUR/USD this week" but "my mean-reversion setup on EUR/USD has a 62% win rate in ranging conditions but drops to 38% when volatility spikes." Tying each trade back to the specific strategy and market regime that generated it is where the real edge in journaling lives. Most tools treat every trade as an independent event, which misses the point.

Also, expectancy broken down by session and pair. Knowing your London session shorts on GBP/USD have negative expectancy even though your overall P&L is green — that's the kind of thing that saves you before a drawdown finds it for you.

**On auto-sync trust:** I was skeptical at first but came around to it. The key is treating the broker API as your source of truth for the *mechanical* data (fills, timestamps, P&L) while keeping manual input for the *contextual* stuff (why you took the trade, what you saw on the chart, emotional state). Trying to manually enter fill prices is where errors creep in and honestly where the Sunday dread comes from.

One thing to watch with the Postgres schema — if you're planning to support multiple brokers, normalize early. The way OANDA structures their trade data vs. MT4/MT5 vs. cTrader is wildly different. I'd suggest an internal canonical trade format and then adapter layers per broker. Learned that one the hard way.

Good luck with the build — always cool to see more developer-traders scratching their own itch in this space.
