Stock scanner

How can we have both Buy and sell scanner run for the same set of stocks. And how the generated list of stocks say one is for Buy and another is for sell. Also the list of stock should be for the cross over today only and not earlier days.

you can open two scanner windows of buy and sell and can run two scanners at a time

Buy Script:
CROSSOVER(EMA(CLOSE,8),EMA(CLOSE,13)) AND TREND(CLOSE,30) = UP
Sell Script:
CROSSOVER(EMA(CLOSE,13),EMA(CLOSE,8)) AND TREND(CLOSE,30) = DOWN
