Yes we can control the risk, it will at our own hand, but we can't control the market and when facing loss might get successive loses hence don't blaming the market because always true but we should learn and making evaluation trades
There is a good chance that one may suffer several consecutive losses. That is a reason a trader should always maintain risk so the account can sustain several losses and if the loosing number of trades are way too many then it would be good to take a step back and reevaluate the method
