So this type of chart interpretation is very simple and is called Price Action trading. I will use a few additional simple indicators on the charts to help me determine what OTHER traders are thinking and use this mentality to support the current price action. These are :-

* Simple moving averages
* Price pivots, support and resistance
* Trend lines
* Fibonacci retracemenets and projections

The idea behind using these additions is that virtually all other traders will be considering these as major support and resistance levels on their charts, and by that very fact will tend to cause the market to stall, or bounce through or off such levels. This is valuable to help understand the potential future of the price action and should be considered. ALL of these indicators though are used as FUTURE refrence for my decision making, and are not to be used as the actual trading decision.
In other words, i am not waiting for a Moving Average cross to make a trading decision to enter the market, however if i see the price moving towards a strong MA level i will consider this fact into my decision as i may be expecting a bounce off it for example.
Fibonacci levels are good considerations for future movement as well, and i will use them a lot. If your not sure what that is, then click the link i have provided above.
