Auxiliary Variables:  Exponential Moving Average (EMA): Alpha = 2 / (Look_Back + 1); EMA[i] = Alpha × Close[i] + (1 − Alpha) × EMA[i − 1]; Index: i ~ Current Bar. Zero Lag Moving Average (ZLMA): Alpha = 2 / (Look_Back + 1); ZLMA[i] = Alpha × (EMA[i] + Gain × (Close[i] − ZLMA[i − 1])) + (1 − Alpha) × ZLMA[i − 1]; Index: i ~ Current Bar. Variable Gain (from the ZLMA formula): If the variable Gain is zero, the ZLMA becomes just an EMA. If the Gain is sufficiently large, the ZLMA tracks the price for all practical purposes (i.e. minimum lag and minimum smoothing). Therefore, we seek a value of Gain that is a satisfactory compromise. To get the least amount of error (Error = Close[i] − ZLMA[i]), a loop searches for the best value of Gain by varying the Gain variable from the lower Gain_Limit to the upper Gain_Limit. The default value for the variable Gain_Limit is 5.

Filter:  Long Signal: ZLMA[i] crosses over EMA[i], and 100*Least_Error / ATR[i] > Threshold Index: i ~ Current Bar. Short Signal: ZLMA[i] crosses under EMA[i], and 100*Least_Error / ATR[i] > Threshold Index: i ~ Current Bar. Note: Error = Close[i] − ZLMA[i]. The Least_Error is an error for the best value of Gain found via a loop which runs barbybar from the lower Gain_Limit to the upper Gain_Limit. In the original paper, the Least_Error is not normalized by the ATR (Average True Range) but by a closing price. This is not adequate for tests on continuous futures contracts and therefore the original formula was adjusted. Mode: The 2phase reversal system (long/short).

Ehlers, J., Way, R. (2010). Zero Lag (well, almost):
All smoothing filters and moving averages have lag. It’s a law. The lag is necessary because the smoothing is done using past data. Therefore, the averaging includes the effects of the data several bars ago. In this article we show you how to remove a selected amount of lag from an Exponential Moving Average (EMA). Removing all the lag is not necessarily a good thing because with no lag the indicator would just track out the price you are filtering. That is, the amount of lag removed is a tradeoff with the amount of smoothing you are willing to forgo.

Connors, L., Alvarez, C. (2009). Short Term Trading Strategies That Work. Jersey City, NJ: Trading Markets:
Most traders use the 14period RSI. But our studies have shown that statistically, there is no edge using the 14period RSI. However, when you shorten the time frame of the RSI (meaning you go much lower than the 14period) you start seeing some very impressive results. Our research shows that more robust and consistent results are obtained by using a 2period RSI and we have built many trading methods that incorporate the 2period RSI […] The lower the RSI, the greater the performance. The average returns of stocks with a 2period RSI reading below 2 were greater than those stocks with a 2period RSI reading below 5, etc.
A/B/C/D
(i) The trading strategy based on the 2Bar Relative Strength Index underperforms alternative momentum models; (ii) The preferred parameters are: 5 ≤ RSI_Threshold ≤ 13; 8 ≤ Exit_Look_Back ≤ 13 (Figure 12).
