Of course it is. No matter how skilled trader you are, (or poker player/or sports expert), you might lose horribly in the short to mid term. No matter how well prepared you are, how much research you do, or good strategy you have, it is still possible the market (cards/result) go the other way and wipe you out. There's an element of randomness and variables you can't control or predict.
Technical analysis and fundamental are just a distraction in these wild markets, shady exchanges, market manipulations and inside practices are not predictable and eventually destroy even the best traders.
Technically, what we do everyday is a gamble. Investing involves and individual risking his/her resources in the right circumstances and then withdrawing it when the right time comes. What makes it difference is we have all the factors to consider and the knowledge to know WHEN to withdraw every investment. Same as trading; people trade and risk their resources for higher profits but they have the power to control their risk and limit the chances of losing every investment. What makes these different from gambling is, even if you have all the techniques and tricks, if the odds are against you then you are surely bound to lose.
I wouldn't say that trading and gambling are the same, because trading and gambling are different by nature.Trade on my Demo account only,then the game ends))
They may be different in nature but all involves something that can be lost and the presence of risk. Anyone can gamble as long as they have the right amount of resources but not everyone can do trading as it involves some techniques and knowledge that can potentially lower the risk of you losing your investments, unlike gambling.
