Are any of you guys trading all in or all out with 20 lots or more?
I'm kind of stuck in the 3 to 5 lot range...not financially, psychologically!
(I don't trade lots of 20s)
Fix your size at 3 cars.
Determine a % increase in your equity that will trigger adding 1 car.
When you reach it trade with 4. If you go below x equity, you reduce one car. If you go above y, you add one car.
Rinse. Repeat.
Going from 1 to 2 and from 2 to 3 is hardest. 3 to 5 still hard. Then it gets much easier. 1 to 2: 100% increase in P&L. 2 to 3: 50% increase... 5 to 6: 20%... 10 to 11: 10%, etc.
Once you go past a high number of cars (not there yet myself

), simply go for a parallel increase/decrease % of cars as percentage of equity. I.e. When my trading equity increases/decreases 10%, I will add/reduce 10% contracts.
And always make sure you take some off the table.

i am at 1 lot....LOL
Anyone with half a brain (or more

) should start there. Some of us started with more because we could... and ended up trading with one car. There's no shame in starting at the beginning.
