You have said it yourself that trading doesn't guarantee regular profits. Matter of fact, I would say, trading doesn't guarantee profits itself.
So considering that many people lose money while trading it wouldn't make much of a sense if we quit our day job for trading.
Surely some people do make money out of trading but even in that case, why not have your stable job and continue trading part time.
Investment is risky, trading is more dangerous so except if you are as either an investor or a trader who already made millions or billions of dollar from investment or trading, and already took it to fiat currency, cash, bought real estates and some luxury things, you should never quit your job.
It's because profit today from either investment or trading, can turn to loss in future if you continue your investment or trading, and don't cash it out all or partially.
It's addictive to continue with trading or investment and because they're both very risky, you can lose your money quickly with them too. Quitting your job, and getting loss later, your life will become very hard.
Besides that, at times when you have spare cash with you, you'll feel like to invest it all which is called as compulsive buying.
I have suffered from it and this can cause your bank balance to vanish. This is another reason to not leave the job when you are making profits.
To avoid this, we must set a strict budget for trading and try not to cross it buying everything we can when the market falls.
We do need some spare money for our basic necessities and emergencies.
Quitting your job or having that resignation isnt something that so simple kind of decision on which at the moment that you do make such option then make it sure that you do have other income sources on which you can be able to rely on because quitting your job is not just some kind of joke and come to think off that getting one is really that too hard due to tons of competitions. This is why before you do make out such decision then make it sure that you are wary about on the potential risks that it does have. Make it sure that you do have those back up plans because if you do quit up directly because of some temporal huge profits in trading then that would really be a suicide. The main key on here to see before you do make out such act is to make yourself that being sustainable with trading on which this isnt something a skill that everyone will be able to obtain or simply this is really that a matter of time and tons of efforts that you would really be that needing. For me on which wont be quitting up my office work even though its really that indeed hassle or that stressful considering with that daily commute but this is where we do able to survive and live. When it comes into a point that you do have that other income source on which earning on more than on what you do earn into your job then thats good but you should be putting up some targets for you to consider on quitting or resigning. For me, i would be stopping or quitting if the time comes that my trading profit is really that able to give 5-10x on my current salary and able to make up some sustainable history in trading for about 2 -3 years maybe, then it will be that sufficient enough for me to tell that im a profitable or sustainable trader. Well, this is really just that my own threshold or limits before doing such act because we do know that this isnt something a joke that you can be able to directly made out such thing.
