Optimized the "day of the week selection" function"

Indicators are built into the expert Advisor

Improved the check of the account free margin for opening a position. Now the check is performed immediately before an order is opened.

The choice of day of the week – select a day of the week when trade is allowed, if not allowed and there are open trades, trading will be continued until these trades are closed.

Maximum volume - maximum allowed volume if the volume increase is enabled (Losing volume, increased by two).

Open a new bar – opening an order on a new bar after receiving a signal of the indicator.
Timeframe of a new bar – the period, on which we should wait for the opening of a new bar.

Not to repeat if the order was closed with profit – do not open a trade if the signal from the indicator is active and the last order was closed with positive profit.

Not to repeat if the order is closed with stoploss - do not open a trade if the signal from the indicator is active and the last order is closed with negative result.

Close by opposite signal – close open orders in case of an opposite signal of the indicator.

Added the Distance option to the settings of the MovingAverage indicator.
Distance - when this parameter is set, an order is opened when the MovingAverage moves from the price to a specified Distance in points, in case it is a BUY signal, and when the MovingAverage moves from the price to a specified Distance in points, in case it is a SELL signal (if Distance=0, this parameter is disabled).
