3. There are special orders for doing these things

Limit orders, contingent orders are like triggers if one thing happens,
another order is entered

OCO = one cancels another

So if your stop at $9.75 is executed, your sell at $11 is cancelled.

OSO = one sends another

so if your limit to buy at $10 is executed, then your limit to
sell at $10.75 is entered as an OSO order
