Account Type and Minimum Lot Size Requirements
The broker account must support retail hedging mode in order for the EA to operate. Note that the netting mode broker account is not compatible with the EA.
A so-called Micro broker account is necessary if the available funds for the EA trading is less than approx. $1000. The micro account allows the EA to open a position with minimum lot size of 0.01. If you plan to use a broker account with the above funding please ensure that your broker account offers this minimum lot size.
An easy way to double check the minimum lot size available on the broker account is to attach the EA to a chart and check the Market Info section on the chart:

The Lot line shows Min:0.01 which tells that the minimum lot size requirement is 0.01 on this broker account.
