How to check whether signal is already generated or not for a particular stock.

Hi,
My requirement is below:
Once signal is generated then i want to store the symbol.Because for the same symbol if signal is generated again then i am checking whether signal already generated or not for the symbol . if the signal is generated second time for the same symbol, i do not want to place order.In amibroker there is no dynamic array of string concept.So how to check whether signal is already generated or not for a particular stock.

Thanks in advance.

You don't need to do this at all. AmiBroker will NOT enter another position if there is already open position on given stock http://www.amibroker.com/guide/h_portfolio.html
