Opening and Closing Pending/Market Orders.

Programmers,

I am currently running a simple EA that open and close orders as per the attache file sections 15 & 16.

Current operation:

The Ea will open or close a pending, only one trade at a time so on opening a Pending Buy will Close a Pending Sell and  opening a Pending SELL will close a Pending BUY.

I would like the following to occur instead;

1.  Opening a Pending BUY order will Close a Pending sell order

2.  Opening a Pending SELL order will Close a Pending BUY order

3. If in a MARKET BUY order a Pending SELL order will NOT close the MARKET order but a SELL MARKET order will close the BUY Market order & visa versa.

4. The ability to close a MARKET order based on other parameters Trailing Stop, other Indicator inputs etc.
