I’ve learnt that with AutoScaling, when position size comes to a fraction >1 like 1.7, its rounded down to nearest integer in this case, 1.
And when it comes to a fraction <1 like 0.07, its rounded up to 1.
Rouding up to 1 may be a problem, because follower’s risk is now increased compared to traders risk - by the ratio of their account sizes. If both trader and follower have position size 1 but trader has dbl the account size, follower’s risk is now two times at half account size.
Its impractical for many followers to have same or higher equity than traders. So we have to AutoScale to get proportionate lots. But then we have the rounding up to 1 problem.
So, how do we deal with this?
