How important is the length of the trackrecord?

I have become consistent enough that I am looking to start trading soon with the hope of attracting investments. (I guess that is everyone here)

I see darwins like this with 500k + investments with just 5months record https://www.darwinex.com/darwin/YIR

Is this common ?

No, it is very rare.
About YIR I think the reason is that we have the same trader than ZVQ , and ZVQ has 10 years of trackrecord.

Normally to attract a significant AuM you need at least one year.
