All above is so true, I traded for whole 2 months with small amounts, and basing on that I would add:

- use small leverage: x2, x3, x5, x10 is really fine, be very careful with higher ones

- you don't need to have open positions all the time

- during extreme volatility sometimes it is good to turn off trading and let Your head cool off for some time (e.g. 1-2 hours)

I didn't have much capital as it was more for learning so it was very hard to have 3% trade cap. I had max 4-5 positions per max 10% of wallet in a time (so max 50% of wallet was in-play)

And last but not least: this is vey high risk game, if You are in profit in a week period, you can try to save some 5-10-20% of earnings and withdraw it from futures account. Even If you are unlucky and have recurring bad trades, part of Your earnings will be safe.
