This is not an easy question.
You can't know for sure where the market is heading. All you can do is guessing and evaluate the probability to get right or wrong and adopt a good risk management.
If you take my own strategy, I'm a swing trader (and mostly a trend follower). I'm looking for charts with a channel.
in an uptrend channel when the price hit the support I estimate that the probability for the price to go up is higher than the probability to go down (I'm often wrong with the probability). I buy and put a stop loss bellow the support of the channel and then wait for the price to go in my direction. My target is often twice higher (at least) than the expected loss. That mean if the stop loss set a risk at $100 then my target is at least $200.
To sum up, When I win I got 200, when I lose the market takes me 100, and I expect to win more than one in two trades, which is not true in real life but that's not a problem I can afford to win only one in three trades to be break even.
