4 Предопределенные переменные

Для каждой выполняющейся MQL4-программы поддерживается ряд предопределенных

переменных, которые отражают состояние текущего ценового графика на момент запуска

программы - эксперта, скрипта или пользовательского индикатора.

Библиотеки пользуются переменными вызвавшего их модуля.

Для безопасного и быстрого доступа к этим данным клиентский терминал обеспечивает

локальные копии предопределенных переменных для каждой запущенной программы

отдельно. Эти данные обновляются при каждом новом запуске прикрепленного эксперта

или пользовательского индикатора автоматически, либо при помощи вызова функции

RefreshRates()

4.1 Ask

double Ask

Последняя известная цена продажи (запрашиваемая цена) текущего инструмента. Для

обновления необходимо использовать функцию RefreshRates().

См. также MarketInfo().

Пример:

if(iRSI(NULL,0,14,PRICE_CLOSE,0)<25)

{

OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Bid-

StopLoss*Point,Ask+TakeProfit*Point,

"Order Buy #2",3,D'2005.10.10 12:30',Red);

return;

}

4.2 Bars

int Bars

Количество баров на текущем графике.

См. также iBars()

Пример:

int counter=1;

for(int i=1; i<=Bars; i++)

{

Print(Close[i-1]);

}
