I don't know anybody who constantly makes money in trading on the stock exchange or in casinos, or at bets! So I think that daytrading and gambling can easily be called similar..
I don't think there is someone who can earn daily in betting or casinos. AFAIK, we don't always win in each attempt in gambling. While in trading, you can earn daily if you don't target too high for profits. On the other side, some gambling games such as dice or slot, require no specific skills since they are luck-based. In trading, especially in day trading, we need specific skills to optimize the chance of profits. You cannot trade with careless skills & no knowledge in trading yet it will lead to losing only. So, how can we conclude they are the same?
They arent the same on general sense yet gambling would really be gambling and trading would really be trading but there are
situation where trading can be gambling if you dont know on what you are doing but gambling cant really be considered trading.
Theres no such thing about fix profit on gambling in daily basis even lets talk on strategy based gambling.
If you do like to trade or investment then all things should really be studied and you shouldnt do it on random basis or does lack
skills and knowledge yet you do basically doing gambling.
