MT4 Expert Advisor To place market order with magic number

I need an expert advisor for MT4 that will place an order with a magic number 1. User decides whether pending order or market order 2. If pending order...then at what price 3. If pending then Type of pending order (buy stop, sell stop, buy limit, sell limt 4. Trade size (how many lots) 5. Magic number is user defined There are MANY EA's that already do this.. however... all of them place more than 1 order... in other words they keep placing the order over and over again. This EA must place only one order every time it is loaded... so for ewxample...if I place a buy EUR/USD now.. and want to place another one later (while the first EUR/USD is still open)... I must reload the Expert Advisor
