Stumbling blocks in new strategies.

The couple of strategies that I have been testing out, has given me very high winning ratios.. However when it goes against you, the drawdown is quite huge thus making the gains negligible... Making it feel like it's a random.. Possibly I might start using a few indicators to see if it makes sense to trade that way..Never used indicators before. Never really get to do any backtesting given all those chart drawings seem so subjective. I have recently googled and found an interesting character in TheRumpledOne. However I can testify that, TheRumpledOne and his strategies, never did work out well. Although, I must add that he does preach some common sense and it will be useful to traders.. He sounded very much like my previous boss in a way.. But all in all, the strategies doesn't work. I have recently talked to someone and he testifies that you can actually pay and buy profitable EAs for metatrader. But they cost a few grand each.. Maybe once I get to a certain size, I will invest and backtest a few.
