Trading Orders in Trading app

How can I block fractunal shares from appearing in Trading view

I would like to see the number in shares starts from 1.00 or 0
not 0.0000000000000000000000001


And also

Which one to choose if I want the order to work in 24 hours for limit orders

Regular trading hours / outside trading hours / and overnight hours

And, Does the stop loss / profit works in overnight trading hours / overnight ?
