People here too easily compare trading with gambling. Trading without basic knowledge is what the bad traders are and they are the traders who will lose money. If the trader is prepared to lose a lot of what he earned, I tend to believe that the trader is probably learning to gain a good knowledge of trading.
Those people who think that trading is gambling are people who go into trading and approach the market with the mindset of a gambler. They don't follow the rules of trading and jump in and jump out which is not so. Before you should take any single trade you must have a proper plan, that is your entry and exiting point, Take profit and stop loss, and must have your terms and conditions of taking trade met and never be in a hurry, trading is a waiting game, when you hurriedly enter the market, most likely you would either hurry out with a lose and that is not how to approach the market.
