I don't think it's important to lose or win for novice traders, but the main thing to do is to be able to trade healthily. we analyze, we have a framework and we are disciplined within that framework. that way we practice analysis, of course money management, and also our psychology. so that in the future we can assess the development of our trading style whether it has progress or not, and of course we can evaluate it for a better future
All you're trying to say is that the novice should win. It mightn't necessary be him winning with his trade but he must win with other habits that'll turn him into a professional trader. Even when he loses, he should be able to learn from his mistakes and work on them so he doesn't repeat the mistakes in future that'll possibly cause more damaging losses.
A trader has to win or his losses will make him give up on himself. A trader that isn't winning would not have the motivation to continue trading. The wins mightn't happen everything but it should be more than the losses that he experiences so he can have a profitable balance sheet.
