Minimum investment

It is important for determining the position size before placing an order. This allows traders to calculate risks, profits and minimise the risks.
Lower the position size, lower is the risk.
 
Minimum investment is the best option for beginners to start trading live. They can prefer trading on either cent or micro accounts. This will not only help them to adapt to the live trading environment but also help in developing trading psychology.
 
I agree. I think the best thing to do is to use a demo account, then a micro account, then increase the investment once you gain real confidence.
