pending orders to market orders ........

 
When i open a pending order it produces ticket number,ordertype etc.and can learn them with orderselect function.

But after the pending order realizes and it becomes a market order,does its ticket number,ordertype change and becomes a new order?and could its ticket number,ordertype etc be learned with another orderselect function?
(for example does its ordertype change from buy_limit to op_buy?
 
The order type changes. Not sure about OrderOpenTime
 
What about order open price? Can orderselect function choose its open price as different?
 
Of course. A pending order becomes a market order when the market touches the pending price and slippage can/will happen. If the market gaps, the new OrderOpenPrice can be much higher than the pending price. Tester does not mimic gaps.)
