UniversalEA

The Expert Advisor allows you to build a trading system based on a custom indicator. It performs automated opening/closing of deals based on the signals of an indicator that places values ​​other than 0 and EMPTY_VALUE in the buffer. The EA polls the values ​​of the specified indicator buffers, opens/closes and accompanies trades according to the specified parameters.

The Expert Advisor implements the following trade support functions:

- installation for the transaction SL and TP;
- calculation of the volume for a given risk;
- transfer to breakeven;
- partial closure;
- increase in the volume of the transaction after receiving a loss;
- closing of all orders by total profit.
