Hello David...

Money management for sure is the most important pillar of trading.
And unfortunately the most neglected.

Bill..
You where commenting an example for the 2% rule .


In my case... from the total amount of my account I calculate the 2% and break it down from there.
Example:

Account Value: 20,000
2% Risk: 400

Which I break down into pieces like this.
for every 10,000
risk: 200

and going deeper...
For every 1,000
risk: 20

It sounds very little when taking in consideration spread cost or/and fees.

What I use this for is to discipline myself on trading proportionally in
accordance to the size of the trade vs the size of the total account.

Won't make sense to risk 200 on a 1000 trade.. Even if 200 is 2% of the overall account, it's a BIG 20% in this single trade.

I might be wrong on these one... But it works for me so far.

Good trading.
