Four-layer Neural Network Expert Advisor based on perceptrons that analyze the opening, closing of candles, the maximum and minimum price for a given period of history. The moving average serves as an additional filter. Several parameters are used in optimization of the perceptron, weight coefficient "x1–x4", optimize from 5 to 100 with step 5 and "y1–y4" bar coordinate, optimize from 2 to 50 with step 2. Optimize on "every tick" on a history of 2–3 months.

The feature of the EA is that it has the ability to change the strategy of closing and maintaining orders right from the built-in panel on the chart. For example, if placing pending orders is enabled, then all trailing functions will work as a whole based on the average price, and not each order separately. If there are multiple open positions, the same stop loss, take profit levels will be set for them, breakeven and trailing stop will be activated for the entire order grid.

The EA can also work manually opened orders and orders opened by any other EAs. This can be applied to attempt to recover the losing trades opened by any other EA or even save the trader form losing the deposit. The Autotrading parameter, if = false, the EA will not open initial orders according to its specified strategy.

The news filter allows to avoid entering the market during the news releases. In order to provide operation of the news filter: In the terminal, open Tools ---> Options ---> Expert Advisors ---> add "http://calendar.fxstreet.com" to the "Allow WebRequest for listed URL list" field.
