HamFon Radar01 SMAStack indicator
for TradeStation 7 RadarScreen
Indicator purpose
Ham SMA Stack displays information about the current price relative to three
Simple Moving Average lines. This indicator looks for the three SMA lines to be stacked,
either in an uptrend (fastest MA higher than middle MA, middle MA higher than slowest MA, and
slowest MA trending up), or in a downtrend (fastest MA lower than middle MA, middle MA lower
than slowest MA, and slowest MA trending down). If a trend is detected, then the price level
is displayed (and color coded by default as green for uptrend, red for downtrend).
The price level is determined by where the current price falls in the SMA lines. For an uptrend,
the price level can be '>=Fast', '>=Med' (but less than Fast), '>=Slow' (but less than Med),
or '<Slow'. For a downtrend, the price level can be '<=Fast', '<=Med' (but greater than Fast),
'<=Slow' (but greater than Med), or '>Slow'.
Settings:General
- Maximum number of bars study will reference - default is Auto-detect.

but the indicator will not be recalculated until the end of the current bar.
- Load additional data for accumulative calculations - default is checked, with a
