My Trade Trend Model is based on charts 15 min to 60 min and points in-between. My fav is a 30 min chart. When market anxiety and volatility rise more weight is placed on faster, shorter time frame charts.
I use:
1) a standard moving average for direction,
2) a non standard moving average for strength and direction of change I designed,
3) a second trend change indicator, and
4) a standard oscillator.
A signal occurs when 3 of the 4 indicators agree on direction. When all 4 line up the signal is said to be confirmed.
This is typically, but not always, a swing trading model, 2 or more days per signal.
A day trading model is based on the same signals but uses two smaller time frame charts, say, a 1 min, and 5 or 15 min charts (for directional guidance) with trade signals based on the 1 min chart.
Daily and weekly charts reveal large trend changes using the same signals, e.g., the bullish move that started in March of 2009 or the shorter move Up that started last month, 15 Feb 2010 and may be about to change presently.
