Can I Sell a scrip higher than CMP and exit the trade when it goes below CMP

Can I Sell a scrip higher than CMP and exit the trade when it goes below CMP

Illustration:

Scrip X is trading at 100.40 / 100.50. You can place a sell limit order for say, 101.50 . When buyers are available at 101.50 your sell order will be executed. You can place a buy limit order for say, 100.20 . When sellers are available at 100.20 your buy order will be executed.

If your query related to a different scenario please elaborate. Cheers.
