1. Check one year daily charts first for long term trend lines which you need to be aware of before buying/selling. Don't skip this step as it often identifies trends that you won't see in shorter time frames. Use a solid candlestick format.
2. Check the 3 month daily chart as reflective of the quarter, which will reveal subtrends that aren't always evident on an annual chart.
2b. Next interpret the last couple candelsticks on the right to "read" what the market is going to do for next market day. Example: Monday to Tuesday trend will give a read on what is happening Wednesday.
2c. Compare the above to the 3 month weekly chart to "read" what is projected for the week. Again, Week 1 and Week 2 candlesticks will indicate what Week 3 is likely to do. All of these together will give you a great read on when to enter and exit.
3. Check the 5 day one 1 minute chart, or whatever is the smallest increment you have available. It makes you aware of current volatily range and short term trends. Finally, check the 2 day 1 minute chart for the same thing, especially in a volatile market like we have now.
Draw trend lines for all of the above, from the lowest point on the left of the chart to the lowest right of it for an uptrend line, and from the highest point on the left of the chart, to the highest right for the downtrend line.
Together you'll come up with a good read. Test your projections each day against what you see. You'll find you'll be pretty good at it after you do this each day. There are a lot of other elements to help you tighten up your projections that you can read, and best learn from actual experience.
Recognizing turning points is critical. If you're not already conversive on the topic (you may be already) get a simple book on candlestick charting to learn how candle shapes, proximity to trend lines, and volume enable you to build a strong projection. Most of the time candles are right, and trend lines only confirm them stronger. Learning how to average candles together for further confirmation, what shapes indicate indecision or push/pull situations, and likely reversals or surges, is very important. And by all means get a subscription to Investor's Business Daily - great stock screens for you to select from, and excellent investor training on pattern recognition and when to enter/exit a position. Read William O'Neill's books. He says more in less words than anyone and is very, very good.
All the best to you!
