yes...daytrading not a hobby...there is nothing simple/Holy Grail for technical trading, sorry
however I have a suggestion.
Measure "cycles" within whatever market you are interested in. You might want to start with the NASDAQ and DOW indexes, going back 5 or 10 years. Look at daily bars, then 10 minute bars. You will definitely notice some interesting patterns emerge on the ten minute bars on the Dow.
Anything written by John Murphy is helpful regarding technical analysis; Wiki has some good (but limited) stuff on technical analysis.
Some terms that you should understand when measuring cycles are :
retracement
retracement percentage
support
resistance
time
price
trendline
Try to find cycles that feature a 100% retracement of a previous Low, or 100% retracement of a previous High.
Then, all cycles within THAT cycle are 'partial retracements' -- look for 50% retracements and 110% retracements (a slightly higher high, or a slightly lower low of the previous cycle).
Measure timeframes of cycles, intraday, multi-day, or month/multi-month.
Uptrends feature cycle lows that have a common upward tilt (trendlines) -- when the uptrend line is repeatedly violated that is a warning that maybe the party is over; or if the uptrend no longer creates higher highs, now good time to take profits. Reverse the methodology for downtrends.
here's a link to something John Murphy wrote "ten laws of technical trading"
Very basic, but extremely useful in focusing your learning.
