[...] of our example Strategy, we take a standard Renko chart and use Daily prices. Despite using the same period, the HA-based average always lags behind due to added smoothing. The rules are: When the 8-period “fast” average crosses above the “slower” counterpart of the same period, a long position is established. When the 8-period “fast” average crosses below the “slower” average of the same period, the long position is closed. Figure 1. A Wealth-Lab [...]
[...] order to analyze variations of the instantaneous phase and amplitude. HTPeriod (or MESA Instantaneous Period) returns the period of the Dominant Cycle of the analytic signal as generated by the Hilbert Transform. The Dominant Cycle can be thought of as being the "most likely" period (in the range of 10 to 40) of a sine function of the Price Series. Interpretation
The HTPeriod at a specific bar gives the current Hilbert Transform Period as instantaneously measured at that bar in the [...]
