The problem I have with the lines is that I am not sure what might be important and what not, so I end up tracing way too many lines. Any suggestions about what to focus on.
That depends on what timeframe you're trading and what bar interval you're using to trade it. But whatever timeframe and whatever bar interval, remember what is in your head and what is in the market. Trend is in the market. But what you use to illustrate trend -- e.g., trendlines, trend channels, etc -- is in your head. Therefore, a violation of support or resistance, which is in the market, beats the breaking of a trendline, which is in your head.
Here, for example, price acted as both resistance and then support at 52, and after the open, it never could make a higher high, never making it past 54. So even though the macro trend is "up" and the line of least resistance is "up", you as a trader always have the option of putting the trend on the backburner and focusing on what's happening in the micro. Here, price couldn't make a higher high, so do you want to assume the risk of shorting all of this, even though support is so close? If you had, you would have made up to eight points. If you had hung on, you might have made more. Or you might have exited and re-entered, even though at that point you were sitting dead on support. What would you have done? Only you can answer that, depending on how honest you are with yourself.
If you're trading the 1m, or even the 5m, the dynamics of what's happening with that bar interval will take precedence. However, if you're not aware of the weekly, daily, and hourly trends and S/Rs, you are far more likely to encounter a lot of What The Hell Just Happened? and lose in your trades rather than remain in control. Here, for example, we are still riding the very-short-term trendline, and though we broke through near support at 40, we're holding at Friday's low. If we break Friday's low, we could return all the way back to the longer-term trendline at 2800. Not likely, but possible. All of this should be running through the analytical processors in your head when you're deciding whether to take a particular trade or not.
