Actually if you are a professional investor, you can earn money both in the bull market and down point. The most boring is a market siderway, not the market down.
In strong declines, there is always the opportunity to go a long way in the opposite direction, so anyone who knows how to play in a down market will be rich quick in a bull market.
The important thing in a bearish market is the trend reversal, so remember that in the bearish market and as close to the important support points you should put extremely short SL. For this reason, you can lose 8 out of 10 orders, but just succeed 2 orders, you will get back all, even profitable.
So for a professional investor, you can make money even in a strong down market.
Prepare yourself for a solid strategy and psychology. Good luck !

Yes people make profit in a down market, I trade at anytime whether the market is down or up. But there is just something you said now and I dont really get it.
What do you mean by making the 10 orders and losing 8 out of the ten orders and then using two orders to recover what you lost, lol. How can only tow orders be enough to recover what you lose, unless you planned going all in or with big funds at the last tow orders.
