#1. Can you trade 1 min candles without stops ?
#2. Can you trade 1 week candles without stops ?
You can do whatever you want in the market, so yes.
However, I would strongly advise you use stops. Stops mean you've taken into consideration that you might be wrong and in turn what that loss will be (slippage excluded). Stops also mean you're thinking the long game and one trade, profit or loss, is basically irrelevant.
I once new a very big trader on one of the floors and his famous quote was 'more money has been lost in the market by people not using stops than by all the other reasons combined'. And guess what, he always used a firm stop.
Anything can happen so you better have a plan (for that) and using a stop is a nice simple plan.
Another point to mention is that when in a position you're in what I call the 'Twilight Zone'. That's a dark place where it's not always easy to make the right decisions aat the right time because of the open-trade.For example, we panic out of a winning trade (don't want to give back) and panic out of a good trade (that ultmatly would have worked) because we 'knew' that out stop was going to be hit. We can also freeze like that deer in the headlights and not know what to do.
A good real-time example of this would be some of the Tesla shorts right now. Yes, Tesla may well be a fraud, who knows, but right now their minds are shot, they're not thinking correctly, all they're thinking is they're 'right' and Tesla/the market is wrong. They're in deep in that Twilight Zone and they're 100% trapped. The only way out for them is if Tesla dumps this week (unlikely) or when they're taken out of the game by their broker because of lack of funds. If/when that happens how they'd wish they used a stop. Losing money shorting Tesla is not a crime as long as the amount lost is small.
Stops protect you from yourself...
