START SMALL

Perfection is often the enemy of progress.

1. Create an OK version of your trade such that you're comfortable with and won't think of commiting suicide or entering into depression if you lose your fund.

2. Start trading

3. Revise and make it better.

4. Then relaunch.

It is better to go live with a Minimum Viable Amount than to spend years creating a PERFECT big amount that may never see the market.
