Profitability increased by 50%

Added a filter for news about interest rates for 2020.

ATTENTION!
Changed the calculation of the starting lot depending on the Deposit amount.
For 1000USD, the starting lot will be equal to Risk Level: Low=0.01; Medium=0.02; High=0.03.
Accordingly, the names of Target profit modes were changed: 10,25,50,75,100. (50% - default)

1. Added the Stop Loss Limit parameter, which sets the loss value at which all orders are closed and trading stops until the START_trade button is pressed
2. Added Risk level = SuperLow mode where starting lot =0.01 to Deposit 2999USD
3. In the 100% mode, the buttons for setting the direction of trade are displayed on the chart
4. Optimized trading algorithm

1. There are provisions for selective closing of orders manually. It is not recommended to close the last orders in the SELL and BUY groups, as they set the boundary condition of the transaction to open the next order.
2. If the Deposit decreases as a result of closing a losing order or withdrawing part of the Deposit, the EA will automatically recalculate the initial lot.
3. On the chart display button CloseSELL and CloseBUY and information about profit orders SELL and BUY

Amended to limit the growth of the lot
