How To Sum Column Base On Few Criteria

I would like to sum the amount column of unique date that is in active status of each account.

Account Date Status Amount
11 jan 1 A 200
12 jan 1 A 5
13 jan 1 A 1000
11 jan 1 A 200
11 jan 3 A 100
12 jan 3 A 8
13 jan 4 A 1
13 jan 4 A 1
11 jan 6 I 50
12 jan 6 A 10

Below is the expected result
Account Amount
11 300 (200+100) [200 is only add once since jan 1 of 11 has appeared more than one time]
12 23 (5+8+10)
13 1001(1000+1)
