That’s a solid and practical guide for short-term crypto trading — very well structured. Here's a quick summary and enhancement of your 3 Iron Rules, highlighting their power:

---

1. Secure Profits, Protect Gains

10%+ gain? Watch like a hawk.

Back to entry price? Exit to avoid round-tripping.

20%+ gain? Don't let it fall below 10%.

30%+ gain? Lock in at least 15% profit.

Key: You’re not chasing the top — you’re defending growth.

Pro tip: Use trailing stop-losses to automate profit protection.

2. Cut Losses Early — No Emotions

15% drop = exit (customize this limit).

Why: Avoid emotional holding hoping for a bounce.

Missed rebound? No regrets — better re-entry than deep drawdowns.

Pro tip: Pre-set your stop-losses, and honor them. No hesitation.

3. Buy Low (Smartly) to Reduce Cost

Sold and it dropped? Re-buy at a discount if belief remains.

Didn’t drop much and surged? Re-enter fast — accept Small fee over missing the next leg.

If it’s too choppy, reassess your entry plan.

Pro tip: Pair re-buys with risk-managed scaling-in — small buys over time instead of all-in.

Final Wisdom:

> “Close enough is good enough.” Perfect trades are rare — but disciplined strategies compound gains over time.
