I don't think you can close the alerts window from the code.

Why, you can click the OK button or the cross in the top-right corner of the alert window to close it.

//-------

orders are assigned a numerical value..... OP_SELL is equal to 1..... the only order less than 1 is 0, which is a OP_BUY.......

you can see the listed values of order properties here..... the mql4 docs is helpful in understanding the code......
//-----

the comment function will put the actual amount the bid is above or below the opening price......
