Spread default on Market Orders

[TraderDesk]

Hi, I was wondering if Empty4 has a script that when I initiate a Market Order that one of the parameters it will look at is spread between bid/ask. As I have spreads that go from 0 to 1.2 pips on GBP/USD I prefer to enter the market at the lowest spread possible.

An example would be I would do a market order buy and I have set the spread <.5 with a time of 7 seconds for order to be sent as it loops on the Empty4 client waiting for the <.5 pip spread to occur. IF within 7 seconds the <.5 spread does not happen the order is canceled. Both the spread value and seconds value should be adjustable.

Of course I know that the spread can go above .5 from the time Empty4 submits the order but I am running Rooicol maintain session EA as well as FX1 MT4Ticker which helps to keep latency down to a minimum...

Has this already been done and if so can you please point the link and if not is it possible to be done by a member here?

Thanks...
