Add EA function 增加EA功能

I bought an EA, and after using it, I found that it is easy to Liquidation and needs to be modified (the specific parameters I used will be provided after the developer is determined).

Modification requirements:

In order to prevent liquidation and need increase the hedging function, (the original EA will open up to 10 orders), please set up a hedge order on the 11th order. The lot size is the sum of the first 10 orders, and the position is 10 points away from the 10th order.

Note:

    a. Hedging order is to prevent liquidation, but it needs to be stop winning.

    b. If the hedging order close, but other orders are not over,  the hedge order need to be reset again to prevent liquidation.

    c. When the hedging order exceeds 28 days without close, the entire 11 orders stop loss, and then let the EA work again.
