Trading Not Going Well

Last three ASX200 trades were stopped out, which is very unusual. The worst in the backtest was two stop outs in a row. Each day the market goes up at the open and puts me into a long position. Then it falls and stops out. Five of the last six trades were losses. I suspect that isn't so unusual. I've done two soybeans trend-following trades and both (long) were losers too. I'm also doing a calendar spread soybean trade which is about a breakeven at this point. On the other hand, we have been doing well in some stocks like Treasury Wine and Domacom.
