Some analysts find that the charting techniquest that they rely on for inter-day trading are also useful for intraday basis. Because of this, these analysts often rely on other charting methods, including point and figure charting and "pivot point analysis." This point and figure charting may be used to plot price fluctuations on an interday or intraday basis.
I never learned point and figure charting, but i know pivot point analysis. There's a great lesson in the School of Pipsology on pivot points, but in short...basically pivot points are levels of support and resistance created by a formula using the previous day's high, low, and closing prices. Pivot points are great way to pick out entry and exit levels, so be sure to check out the lesson and i think you'll find a lot of information to get you started.
