Not sure if this fits here — but I wanted to save a few newcomers some months of suffering and lost cash.
**Quick background so you know where I'm coming from:**
* Crypto trader, so I'm on the higher end of the risk tolerance spectrum
* Trading algos for a few years, net positive (no island yet, but not bleeding either)
* Coming back to it after Binance Futures got disabled across a chunk of Europe
Here's what I wish someone had told me earlier:
**1. Use Freqtrade** Seriously. It eliminates a whole class of stupid mistakes before they cost you real money. Order management bugs alone can wreck you — don't reinvent that wheel.
**2. Run daily reconciliation** Every day, backtest the same period and compare it to your live trades. If they diverge — stop. That gap means something is broken: data, logic, or execution. Fix it before you scale.
**3. Trade small for at least a month** No exceptions. You don't know what you don't know yet.
**4. Overfitting will kill you quietly** The more data and market regimes you test on, the better. A strategy that works on 3 months of one coin in a bull run isn't a strategy — it's luck with extra steps.
**5. Learn the Sharpe ratio — and be suspicious of it** It's the best single number to describe how you're doing. But if yours is above 3, you probably miscalculated it.
Before you get too excited about your results, ask yourself:
* *Made money for 3 months?* Cool. How does it look over 3 years across different market regimes?
* *Works on a single asset?* Great. Why does it fall apart on the next 3–4?
If you can't answer both of those confidently, you're not ready to size up.
Good luck — hope this saves someone some pain.
