Lesser amount of trades normally doesnt translate to good profit. The amount of money needed to be put at risk to know if a trade will work is proportional to the tf traded. Higher tf normally means wider stoploss. And lack of movement is going to kill any system. Issue is damage control. A time tested ema crossover on eod like sh's 315 is whipped 5 times this month.
Every time i place a trade with 6 point point sl... thats the money i am willing to risk to know if the trade will work. 5 such trades fail, I loose 30 points plus brokerage. Same trade with 30 points sl can give it room to move in my direction but all i need is 1 such failed trade for a 30 point damage.
Every thing depends on how i manage my exits. with smaller sl, i have far more number of scratch trades and small loosers. But a small number of big winners is needed to offset all that.
With a wider sl...i cannot afford to be wrong too many times....!
