Насколько я понял, это функции, которые, при использовании в некоторой комбинации дают возможность купить или продать внутри бара. Выписку из описания прилагаю :
LimitIfTouchedOrder (Function)
image\trumpet2.gif Disclaimer
The LimitIfTouchedOrder function is used to configure and send a limit if touched order using the order entry macro .PlaceOrder. You can call this function directly from your own EasyLanguage code to simplify the formatting and generation of macro orders.
Care should be exercised when calling this function as it is intended to send live orders. Confirmations for macro-generated orders can be configured by using the File -> Preferences -> TradeStation Order Entry menu sequence.
Syntax
LimitOrder(Frequency,Account,Action,SymbolCategory,Symbol,Quantity,Duration,GTDDate,IfTouched,LimitPrice)
Returns (Integer)
LimitIfTouchedOrder returns 1 if called on a "real-time" tick and if a trade is allowed based on the user input "Frequency". The function returns -1 (negative one) in other cases; for example, if the function is called on an historical bar. If there are errors in the order parameters a runtime error message will be generated and the order will not be placed.
Как правильно пользоваться - до конца не понял, поэтому решил спросить... Заранее спасибо!
