Good Morning.
I am new to awk so please be patient.

I have a files that looks like this:

QQQQ "QRST 1212" SELL 8885.00 0 3 09283000
QQQQ "QRST 1212" SELL 8900.00 0 1 09460800
QQQQ "QRST 1212" SELL 8905.00 0 5 09465600
QQQQ "QRST 1212" BUY 8900.00 2 0 09484400
QQQQ "QRST 1212" BUY 8915.00 10 0 09501500
QQQQ "QRST 1212" BUY 8915.00 4 0 09511300
QQQQ "QRST 1212" SELL 8950.00 0 2 10465900
QQQQ "QRST 1212" SELL 8950.00 0 4 10491800
QQQQ "QRST 1212" SELL 8950.00 10 0 10491800

QQQQ "QRST 1212" BUY 8960.00 16 0 10491800

My Goal is print out a list with the same price ($4) Quantity ($5 or $6) and time ($7) only if $3 is different in the next row.

Output would look like:
QQQQ "QRST 1212" SELL 8950.00 10 0 10491800
QQQQ "QRST 1212" BUY 8950.00 0 10 10491800
QQQQ "QRST 1212" SELL 8950.00 10 0 10491800
QQQQ "QRST 1212" BUY 8950.00 0 10 10491800



Any help will be appreciated!
