Kindly help, need afl code

i need an afl code which give the signal (any small symbol over/below candle) on the candle of lowest volume for every last 10 candles. for example , if you look at todays bnf chart ( 3min tf) , every big move happened after formation of lowest volume candle (10.21 am, 12.57 pm, 2.42 pm).

For the above condition you can use filters in amibrokerĀ AFLĀ 


Filter = Close < 3 AND Volume >50000;
