Just listened to Brannigan on Axia Futures,
He talked about 11 Habits of successful traders
One of them is “Risk Warmup”,
You don’t start the day with your full size.
Reminded me of a FutureTrader71’s talk on risk.
He introduced the concept of
intraday margining.
My interpretation of this …
1. You need to know your maximum size
2. Define your Maximum loss & Minimum profit
3. Current PnL which is within above parameters
Let’s say your maximum size is 10c
Your Max loss & Min profit are 1,000$
Based on this (
Proprietary 
) formula:
(Max loss + PnL) / (Max loss + Min profit) x Max Size
If current PnL is -500$
Your size should be 25% or 2c
(1000 + -500) / (1000 + 1000) x 10c
If current PnL is 0$
Your size should be 50% or 5c
(1000 + 0) / (1000 + 1000) x 10c
If current PnL is +500$
Your size should be 75% or 7c
(1000 + 500) / (1000 + 1000) x 10c
If current PnL is more or equal to +1000$
Your size should be 100% or 10c
(1000 + 1000) / (1000 + 1000) x 10c
The goals being:
- To avoid hitting your max loss with full size
- To trade less at your worst and more at your best
