This script measures cumulative 'Energy' in a security built up over time where bulls add to the cumulative energy and bears reduce it. Changes to this cumulative energy result from the battle between bulls and bears and can give indications on major turning points as well as signals as to when to enter into a long or short trade. This indicator must be used in conjunction with other techniques.
OUTPUTS:
Area chart: longer term cumulative energy model
Histogram: primary energy model where green positive bars indicate positive energy through the lookback period and red is negative
Line chart: signal line used to identify entry and exit points
INPUTS:
Source Data: Data series to use for calculation of energy changes (O=Open, H=High, L=Low, C=Close). Default O/H|L is best for most markets, but some highly trending or volatile markets may require a different methodology. User should experiment with a security and choose based on its effectiveness in the history
Methodology: Moving average or range based calculations through the lookback period.
Volume Weighted: Not usually significant but can be useful adjustment for securities with low liquidity levels

USAGE:
Blue signal line is the most important indicator and changes from positive to negative or vice versa indicate potential entry and exit opportunities. Users should beware of divergence between the signal line and the energy pattern (histogram) for potential false positive signals.
For example when entering a long position, a good signal is when:
(1) signal line is crossing the zero from negative to positive
(2) energy has been rising consistently for past 3 candles
(3) energy moves into positive at the same time as signal line crosses
(4) longer term energy is increasing (area chart)
Users should avoid using this indicator for entry/exit decisions where there is an absense of a clear trend
User should also take caution where major peaks in long term energy occur which often indicate a period of sideways price movement and increased price volatility. This can be used as part of an options trading strategy but the author has not tested (next version!)
