you're right

hi

Wrote this guide, hope it helps. I am not affiliated with moomoo. guide based on Android phone.
Go to the quotes page and select a stock e.g. MRNA. Then, swipe the top menu to the left ( see arrow) until you see 'Options'
Tap the options button. The options chain with all the strike prices appear. Expiry dates are right above the strike price header.
Select the expiry dates you want and then tap on any of the strike prices below, on either the call or put side, depending on what you want to trade
Tapping either side on the relevant strike prices brings you to the individual option's chart
Once there, tap the 'More' button on the bottom right hand corner
Once tapped, select 'Paper'
you will then be brought to the paper trading interface for that particular option. set your order type, quantity, and paper trade! :)
Hope this helps!

I'm trying to understand the call and put option.
Please correct me if the below is wrong.
Much appreciate for your reply and explanation.
Buy call options = Buyer get the premium immediately? buy at the higher than current price which expecting the price will raise in future?
Sell call options = Seller pay the premium immediately? Why need to sell it if price expect to raise?
Sell put options = Seller get the premium immediately? sell at the lower than current price which expecting the price will drop in future?
Buy call options = Buyer pay the premium immediately? Why buyer choose this?
Which one is able to buy or sell in order to receive the premium?
