If you are trading based on luck, then you should know that you are gambling in fact Then it is impossible to do trade and get success as well Our first preference should be our skills then luck help some time but skill help full time rather than but we have to learn about it and have to collect the skill of our own. in my point of view luck and skills, both are necessary for trading as well bles you to makes money consistently in this market, its true that luck can makes you win regardless on whatever happens in the market.
