The Long-Term Trend indicator is based on a RSI Indicator applied to the weekly chart of S&P Cash index. This indicator does not change from bullish (green arrow) to bearish (red arrow) very often. It indicates the overall U.S. Market bias. Thus, a green arrow indicates the market is likely bullish to a general rise over the coming months or years.
The Short-Term Trend indicator is a more complex indicator applied to the weekly chart of the S&P 100. This is used to help pin-point pullbacks within the overall trend as defined by the Long-Term Trend. Buying weakness (red arrow) when the Longer-Term trend is up can often be seen as a buying opportunity.
Historically the months between October and May see the best returns for any given year. This phenomenal is know as the seasonality bias. This seasonality indicator could be used as a filter applied to both automated trading systems or even discretionary trading. It may not be much help for intraday trading, but it may be worth testing.
