Real traders does not really care about the bear and bull market because they take advantage of every opportunity that comes to the market, they see both bear market and bull markets as an opportunity to make profits, but not everyone can succeed in it though, I'll say it's only those who understands there fundamental and technical analysis because both works together. Bull market are best for long term investors or holder's while bear market are also best for day traders on future trade because they have opportunity to short there trade when they know a market crash is about to happen. And another thing is understanding your support, resistance, and market volatility; if you're good at them, then you should be able to cope in any presents condition of the market
