Don't Mix The Books

My trading and my investing are completely separate books (different assets, strategies, time horizons, execution mannerisms), and keeping them separate allows me to remain sane through market extremes.

The trading book is XAQP: systematic strategies on FX, indices and metals, risk-bounded, stress-tested, monitored daily. It exists to generate performance (in my words; Cash). Every position in it is there because a tested rule put it there, and every rule earned its place through validation. That book is a machine that I built, and I relate to it the way you relate to a machine (check the gauges, service the parts, don't argue with it).

The investing book is the opposite temperament. Long-term positions in equities, ETFs, Metals & Crypto, built slowly, checked rarely. No leverage. Its job is to compound over years while I get on with my life. Performance fees from the trading side flow into it, which is the flywheel I keep coming back to: the job pays the bills, the trading book generates fees, the fees become long-term capital, and the long-term capital is what actually changes your standard of living over a decade.

Why I Keep My Books Separate

Why bother separating them so hard? Because each book fails when you run it with the other one's mindset.

Treat investments like trades and you'll watch them daily, cut winners on volatility, and turn a ten-year horizon into a short-burst sequence of nervous decisions. The whole advantage of the long book is that it doesn't need you. Micromanaging it just totally eliminates that advantage.

Treat trades like investments and you get the opposite failure: "it'll come back" applied to a leveraged position. A systematic book has no room for conviction holds. The rules manage the exit, and the moment you override one because you believe in the position, you're running an untested strategy with live money.

Different Jobs, Different Mindset

Different jobs, different risk, different mindset. The trading book is judged on risk-adjusted return and drawdown behaviour. The investing book is judged on whether I left it alone long enough to do its job.

If you trade and you're starting to build wealth from it, this is the structure I'd think hard about. Two books. A wall between them. Let the machine be a machine and let the compounding be boring.
