Backtesting 2 Ema's crossing

I have been looking at using a simple strategy on the Euro Usa. On the 15 min chart enter a trade on the open of a candle after a 21 Ema 55 Ema cross. With a 30 pip stoploss and a 40 pip tp. Or at 40 pips take off half the profit move the other half to break even and catch the longer runs. My question is if its possible to backtest a strategy of 2 ema's crossing either manually or using backtest software?
Thanks in advance
