How to fill in GCT from shares in HMRC self assessment account

Dear, May I know that what if as follows: 1) If I bought A stocks 100 shares on 10/2/24 and 200 shares 12/2/24 and sold all on 20/2/24. So, which day do I fill the acquisition date? 2) How to fill in the acquisition date and disposal date of the remaining stocks section 104? 3) If I bought the same A stocks in two different brokers, do I need to follow the date sequence to calculate each transaction? Thanks

Please refer to :  Shares and Capital Gains Tax (Self Assessment helpsheet HS284)   and in particular the S104 example  . Thank you .
