yes in fact personally I think opening a position without analyzing is betting and surely it will result in loss although some profit may happen by pure luck. we have to learn the system if we want to be in this field on a long term basis. dear of course I think the main think is money management. its most important factor.if any one open trade with proper analyses with out of money management in this case if price move more pips opposite to their trade then it will lost all his money.
