What is martingale?

This is an automatic increase in the volume of each extra order by a factor of 1.05 to 2. So every subsequent extra order will have bigger volume than the previous one. It helps regain the value lost during unfavourable market conditions.

For example:

We choose martingale = 2 :

First order - $100, first extra order - $200, second extra order - $400, etc.

This is a high-risk option best used by experienced cryptocurrency traders: you may have more benefits but you have bigger sum of your funds involved in the deal.
