can any body help me

hi as the head line i need a help i m using a crack version of amibroker i want to back test a specific stock
i use 50 wma high & 50 wma low
the rule is
BUY:-when price cross 50 wma (high) from down to up & second candle break high of first candle
SELL :-when price cross 50 wma (low) from up to down & second candle break low of first candle
BUY stoploss:- 1-2 point below 50 wma (low)
SELL stoploss:-1-2 point below 50 wma (high)
so i want to back test this strategy
and find how much profit we can make
so pls if any one know pls explain step by step so i can test my another strategy also
