Half a year of prop firm challenges: what I learned about my own discipline

Over roughly six months I ran prop firm challenges across FTMO, BlueGuardian, and two smaller shops. The point was to be evaluated against external rules — daily loss limit, max drawdown, minimum trading days, profit target. The point was not to learn about markets; I had been trading my own account for years.

I learned almost nothing about markets. I learned a lot about myself.

When I broke my own rules

Always in the same conditions: after two losing days in a row, or after a single oversized win on day one. After losses I revenge-traded. After early wins I sized up because "I had a buffer." Both moves felt rational in the moment. Neither survived a screenshot the next morning.

What worked

The boringest system always won. Fixed fractional sizing, one setup, two pairs, three sessions max per day. Anything more elaborate than that — anything that required me to make decisions under fatigue — bled the account.

Simplicity is not a strategy choice. It's a meta-strategy choice about your own discipline.

What I would tell past-me

• The challenge is not against the market. It's against the version of you who is bored at 3pm.
• Daily loss limits are a feature, not a punishment. They save you from the version of you mentioned above.
• If your setup requires a screen full of indicators to confirm, the setup is the problem.

I passed a few. I blew a few. The number that matters is not which firm I passed — it's that my own retail account got quieter and more profitable after the experiment ended.
