I've never understood why people start out trying intraday. Use 3 time frames. Weekly, Daily and 4hr. Decide which day to buy, and use the 4hr stick to time the buy. Make sure it's all in the direction of the weekly momentum. Otherwise, wait. Learn about negative divergences. As price moves towards support/resistance, learn about M's and W's. There are many types. Then learn about relative M's and W's based on momentum (%b is a good way to identify). If price moves in V shapes, wait for another setup, as it's gone. It's really not rocket science.
Figure this out before you go shorter time frames. Or, you know, you could continue to bang your head against intraday without understanding these concepts. Either way, it's your time and money.
Are you taking your trades based on charts only or do you take fundamentals into account?
