You may find the answers to many of your TA questions on the main thread which I linked in this thread's header.
The three most valuable TA tools you can learn to read and apply are Stochastics, MACD and Japanese Candle sticks. Trend lines are also important.
The above mentioned indicators work equally as well regardless of the time frame you are working in. I like to use daily charts to find momentum plays and once I make entry I stay in until the daily indicators tell me a stock is getting technically tired. I will then look at the indicators on a 15 minute, 5 minute and 1 minute time frame in an attempt to pick a selling top.
The links in the main thread header "Ask Vendit" contain a wealth of information and is where I educated myself on TA.
The people who post on that thread are of varying levels of TA expertise, most are very good technicians
and to top that off........all are very nice people who dont mind sharing knowledge with others.
I put this thread up as a tool to scan for stocks that appear technically ready to break out to the upside.
On to your MAC question, I think this better addressed by either Carolyn F or sndiego (Donna).......they both work on a MAC.
