Just started looking at strategies in TA and had a couple of questions that I hope you could answer, I may be asking daft questions though.

If I set an SMA of say 30 and 60 what time period do I set the underlying chart for eg say looking at HBOS do I set the time period for 1 year or longer or shorter. Or does this depend entirely on whether you are looking at short term or long term.

Then when looking at the chart to get in is it sensible to see if the price line drops or goes above the longer of the SMA's.

Is it sensible to also review trend lines and resistance levels to make sure the assesment is accurate.

Also what is crossover is this when 2 lines of an SMA cross, one going up and one going down.

Finally does anybody know where you can get free charts for intrada DAY FTSE, DOW and CAC I just have a theory I want to review to see if I am correct with my thoughts.

Thanks in advance and apologise for all the questions.
