Ryan Jones Fixed Ratio Position Sizing

[nickmccomb]

My problem:
I have implemented Fixed Ratio Position Sizing in 'Volume Sizing' in my pending orders. The unit size is 1 and the delta is 2500. I started with $1000. I have got to $6500 and my unit size hasn't doubled.

What I tried:
Getting my account profit > delta parameter ($3500) and seeing if unit size doubles

What I expect:
It should have doubled the unit size at $3500 and $6000.

My platform:
MT4 Pepperstone
