No.
For me, gambling is based more on chance. Whereas good trading is based on probability.
Sure, you predict with a high level of accuracy when it comes to gambling. It doesn't take a rocket scientist to figure out that England would beat Canada in the RWC, or that Chelsea are likely to beat Derby the next time they meet in the league, or that the FA would sack Steve Mclaren after England failed to qualify.......the educated sports gambler would have seen the 3 likely outcomes immediately.........
However, these are all but dead certs, and the odds the bookmaker offers, would reflect this.............
In trading, you do not get odds, you simply get a spread/commissions that yare usually the same at all times, as you decide to enter/exit the market...........
So the trader with a solid entry & exit strategy, is trading when the "odds" are stacked in his favour, but he is not being penalised for betting on a dead cert.
If you look at another type of gambling such as the casino, I don't know an awful lot about it to be honest. But it seems that its more of a 50/50 chance thing - i.e. the roulette wheel, something which you do not have any control over - i.e. through past performance - it comes down to 50/50 look.
So, if the trader is a novice doesn't have a clear, well defined entry & exit strategy based on past performance/market dynamics/probability of success etc., and is relying on the gods to be favourable with his trade, I see this as gambling.
Trading becomes trading when the entry & exit strategy used is based on clear solid objective researched principles - i.e. backtesting/past performance - through which you can look at the ratio of winners to losers etc., a market dynamic that you have discovered (eg. EURUSD always drops 30 pips at midnight
), and the probability of success with continued implementation of that strategy is better than a 50/50 shot in the dark.
