@stephane97490 Short answer: Nope
Long answer: This strategy opens long only trades, to profit from the constant upwards drift of the market, which is just the fact that market is based on the work of hardworking businesses who constantly tend to produce more value than there was before. Essentially, if you pick all of the assets and long trade all of them in equal amount forever, you will make slightly less money over time than the above script. At daily time frames this upwards drift dilutes to zero, and you are left with fluctuations around the mean. While it is safe to bet on the overall market growth over months and years, daily fluctuations are not as easy to predict. So this would not work at hourly or daily time frames.

Yes the reason was that! indeed I have changed the file "AssetsZ9.csv" putting the value "0" in column "Spread" and "Commission" and now the result it is OK ! Transaction costs 0 spr, 0 slp, 0 rolThanks A lot!! Good Night

@Hredot Re your DualMomentumV1.0 script, I have a couple of Qs. There are two classes (A) Technical, (B) Comparative. A. TECHNICAL(1) Kudos for making it public. Fascinating write-up. THX!
(2) How far back was this tested (vs. Z9) (did you succeed in starting earlier than 2008)? (3) Have you optimized ‘myDaysUpdate’, BarPeriod, etc.? (4) How did you select the Stop ATR TimePeriod, and the (x3) coefficient? (5) What is the percentage of losing trades closed by the Stop Loss feature prior to reaching the rebalance event (@myDaysUpdate)? (6) Did you try making the Stop trailing? B. COMPARATIVEWe back tested a strategy similar to Antonacci's GEM, wo leverage and wo Stop Loss. Every month (Jan 2008 thru Sep 2017) we sorted the recent 12 months returns of BIL, CWI, and SPY and invested long in the highest returning instrument (if BIL showed the best return, we invested in AGG). Our back tested CAGR was 5.7%, while Antonacci reported (here: https://www.optimalmomentum.com/gem_trackrecord.html) on 7.85% for the same period. IMHO, there is a significant gap than demands clarification. I am interested to know if you were successful in replicating the results reported by Antoncci? Rgds,

Hi Mook_Yon! A1) Thanks! A2) No, unfortunately I only went back to the end of 2008, since I did not experiment with other assets. It might be interesting to check the code before 2008! A3) BarPeriod is set to 1 day since that is the most easily available data format. Since the time frame of momentum is one year, this should be fine graded enough. I did play around with the myDaysUpdate setting and 15 seemed to produce better results than 20 or 10. However, I did no rigorous statistical analysis to support this. A4) The ATR TimePeriod and x3 coefficient are selected such that the stop loss does not interfere with any of the trades performed in the backtest. The logic is: the algorithm is supposed to work without stop loss, but we cannot be sure that the market will not completely collapse within a period of 15 days some time in the future. So we put a stop loss in place at a very far distance just in case. Ideally it will never be triggered. A5) 0% closed by stop loss. A6) Nope, since it is only a precaution, not an applied feature. B) I'm not sure about the assets you describe. However, we can perform a backtest of DualMomentumV1.0 between 2009 up to today without leveraging. To do that, we just have to open AssetsZ9.csv file in History folder in the main Zorro installation directory and change all leverage fields from 2 to 1. And set e.g. StartDate=2000; in the script (it will only start in 2009 though, since the history of assets used starts at end of 2007). The result is 8.83% CAGR which can be reconciled with the 7.85% by Antonacci (his value is a bit lower, since his trades have to endure more of the bearish period during the last big crisis).

Thank you Hredot! Coming from Value Investment background, after reading Antonacci’s Dual Momentum book, I desperately needed a “sanity check” method. I wished to use Zorro in order to reproduce, and validate Antonacci’s published back test performance. Unfortunately, using your code, I could not yet validate or re-create Antonacci’s claim to fame (CAGR). In his Dual Momentum Investing (chapter 8, under the subtitle “HOW TO USE IT”), Antonacci provides a detailed framework of the strategy: look back 12 months, rebalance monthly, at any rebalance invest the entire account balance in a single long position, use IVV or VOO for US stock, and VEU or VXUS for non-US, and finally BIL for checking T-bills (AGG, BND, or SCHZ should be purchased when BIL was the best performer). Looking at you code, there are plenty of detours from Antonacci’s Dual Momentum framework: usually positions are gradually entered long, leverage is employed, multiple (best past performers) positions are held simultaneously, etc. Back testing your (greatly done) replica of Z9 (with the initial Z9 asset list) though, produced very nice returns and forum members may consider using it live. Thanks for that!

Thanks for sharing! I have tried to use it, but the trades are not entered. Does "enterLong();" work with IB or another instruction is needed? Or I may added the wrong ETF to IB. I am using the asset list of the z9 system. This is what I get. Download CSJ.US.. 2720 bars read [638: Tue 17-10-31 04:00] (105.2700) enter trade !Order Message: BUY 1 XBI ARCA Warning: your order will not be placed at the exchange until 2017-10-31 09:30:00 US/Eastern XBI-STK--0--SMART--USD (XBI::L) Can't open 1@83.80 at 04:00:01 enter trade [SMH::L] Skipped: Lots 0 enter trade !Order Message: BUY 2 ITB BATS Warning: your order will not be placed at the exchange until 2017-10-31 09:30:00 US/Eastern ITB-STK--0--SMART--USD (ITB::L) Can't open 2@39.36 at 04:00:01 enter trade !Order Message: BUY 1 XLV ARCA Warning: your order will not be placed at the exchange until 2017-10-31 09:30:00 US/Eastern XLV-STK--0--SMART--USD (XLV::L) Can't open 1@82.14 at 04:00:01
