Classification of Popular Indicators ☐ ☐ ☐ ☐ ☐
Winning Chances Test • Data: Industry ETF（15 minutes） • Vertically: for each indicator, choose three long signals and three short signals. Judge the winning chances by seeing the actual trends after the signals. • Horizontally: 5 days, 10 days, 20 days and 50 days • Calculate the actual returns at the end of each period, and then compare it to the pre-determined return standard for each period to see the trends. • The pre-determined return standard is: 2% for 5 days, 3.5% for 10 days, 5% for 20 days and 10% for 50 days. (Note: The result of calculation doesn’t show the real winning chance since it is calculated from only the end of the period.) LongSignals ①②③ 5102050 Duration ShortSignals ①②③
Winning Chance Test: MACD Long Signals: DIFF and DEA are both greater than zero, and DIFF is going up DIFF goes up across DEA from below DIFF goes up above zero Short Signals DIFF and DEA are both smaller than zero, and DIFF is going down DIFF goes down across DEA from above DIFF goes down below zero Long Point 2) Long Point 1) Long Point 3) Short Point 3) Short Point 2) Short Point 1) DIFF DEA

Winning Chance Conclusion Eliminate vertical comparison elements (The difference between different signals of the same indicator) DMI KDJ
Winning Chance Conclusion • KDJhas the highest winning chance in up-trend tests • DMIhas the highest winning chance in down-trend tests • MACDis stable but lagging • BOLL is unstable and has low winning chances Profit/Loss Ratio Test
Profit/Loss Ratio • Test Standard: • Draw distribution of returns at all signals • Cut 20% of the left tail of the distribution • Take average of all positive returns and negative returns, and then find the ratio of the two means
赔率测试 • NoRegularity,hardtochoose • Closeto1.5,whichisacceptable • Stabledistribution,lowvolatility • GiveWinningChancemorepriority BackTesting
Back Testing Signals Profit/Loss Control KDJ 3%Return KDJ -1%Return
Back Testing- Conclusion • Comparing to others, Medicine ETF has greater amplitude, obvious rises and falls, regular fluctuations, and most importantly, it doesn’t have many continuous rising, falling and sideway markets. These are the very properties that determines its compatibility with technical indicators. • During a sideway or continuous rising market, KDJ is too sensitive to small rebounds and recoveries so that it sends out wrong signals. • During a sideway or continuous rising market, ADX line in DMI is also too sensitive to small changes thus sends out false trading signals. • In addition, when the indicated trends are not strong enough, they may result in losses if they do not reach profit control point.
