Yes but not at the expense of your constant loses, we try to keep it going regardless but we should be mindful and know when to stop.. it's just seems like gambling you're pushing in for positivity but then there are factors limiting you to do so and hence you don't want to give up. But when you know the trading system isn't for you it's better to stop rather than having waste of funds .
There should be a limit to how far someone can push himself. Like in trading, if someone is just starting up, there should be limited startup capital, which, if they are unable to get something out of it, they can take a break to learn more first or, better still, look for something else to do instead of making more deposits and sinking it into the broker when they don’t have all it takes to get it all back again.
