1. RISK: the biggest thing wey separate gambling and trading na risk, for the two risk dey sha but with trading you fit control your risk, too many parameters and avenue dey to control your risk, for gambling the chances to control risk dey very slim.
When it comes to risk, I don't see much different between trading and gambling. Both involve risk just as you have said. I'm into sport betting, and nowadays punters can use the cashout bottom to terminate games if the games is going against them. This help to stop the betting, giving you part of your money. To me, this is somehow similar to that of stop loss from trading. Another one is the one game cut bottom, This helps when a single game spoil your accumulated game. So both trading and gambling help in managing risk but just in different way.
I think that there is a difference between trading and gambling because in gambling you have no control over what happens to what you have predicted to happen while in trading it's a different game because you have a control of your trade it's all depends on you if you have a mastery of the forex market because for you to be successful in the forex market you have to have a good practical knowledge of the forex market, so in terms of the risk involved in the two trading is less riskier than gambling because you have control of what really happens to your trade
