Set signal expiry

[[Deleted]]

Hello everyone. I'd like to learn how to set a signal's expiry in EA's. Such that the signal is nolonger traded after, say four bars. 

I will appreciate your help.

I think it’s easier to describe the algorithm in words:

• when you opened a position (you need to catch a position in OnTradeTransaction, catch the transaction TRADE_TRANSACTION_DEAL_ADD, catch the deal DEAL_ENTRY_IN) remember the time the bar opened (let it be the variable m_lasd_deal_IN).
• in the signal module (if a signal appears) you are requesting four values using CopyTime . Compare the time m_lasd_deal_IN and the resulting array

I get the idea but it is still a little unclear. I'm good at following written codes. Please attach an example
