12/21/2020 1:45:15 PM For all in search of backtesting filters here's the link: http://academy.edgerater.com/tradetestguide/ Ed S. PS His simple scripting language can do a lot more than SFs |

12/21/2020 7:30:48 PM @nibor100 The MORE I became accustomed to SF, the MORE I appreciate its simplicity in syntax. Currently, my biggest grievance against SF is the lack of support for "chart-display is MONTHLY" but I'm willing to live with SF even with that grievance. The things I liked especially about SF are: 1. ability to draw horizontal price lines (say day position(0.2, 30) and day position(0.8, 30)). This can NOT be accomplished very easily on Stockcharts.com AT ALL. And the advantage in doing this is not only HUGE but also next to impossible to be over-exaggerated. 2. built-in support for linear regression intercepts/linear regression bands, time series forecast, etc., etc. The discovery of the power of DMA is very recent and accidental. But when combined with #1 above, it seems to me that the need for backtesting has all of sudden evaporated. 3. yes, a few well-known indicators such as the KAMA/adaptive MA, Hull Moving average, etc. are noticeably missing. But the combination of DMAs and #1 above can make every other missing indicator a very minor inconvenience at most, except the monthly charting capability. 4. with such powerful built-in tools as cema, cma, clri, etc., etc. SKY alone is the limit to one's imagination. |

12/22/2020 2:03:43 AM @styliten, That's an interesting response to my Edgerater post.... a. In your point 1, to me it seems that you actually accomplished the "impossible", which iwas over-exaggeration of the impact of 2 horizontal lines drawn on a SF stock chart. Also I found it curious the use of the 2nd parameter being 30 days when you seem to have a desire to look at monthly charts which would be somewhere around 22 trading days. b. Regarding your point 2. my limited imagination is not seeing how I could replace a backtest of say an RSI(2) trading strategy combined with Wilder's Directional Movement Indicators with your 2 suggested lines and the use of SF's DMA indicator.. Perhaps you can provide an example of a replacement for a 3 year backtest of some strategy, so I can better visualize? c. Regarding your point 3, I suspect that many traders who consistently use an indicator, that is not in SF, are even more inconvenienced by the missing indicator than by the missing monthly chart capability; especially, since even the SF weekly chart capability seems to only be usable on a visual basis due to the wonkyness of using weekly parameters as filter criteria. Clearly you and I see things a bit differently, Thanks, Ed S. |

12/22/2020 9:10:52 AM Thank you Ed for sharing! That is one impressive Excel based tool. Have still to figure out how to backtest your own idea but its got some cool templates included. |

12/22/2020 1:41:47 PM @nibor100 The reason that horizontal price LINES based on day position formula are the holy grail is because they can be viewed as the dollarized volatility benchmarks. In effect, dp(0.2, X) and dp(0.8, X) are very similar to the 30/70 lines in RSIs. When X = 30, that's 6 weeks, or about 1/2 of the 13 week quarterly trading cycle. |

12/23/2020 2:17:55 AM @VirginTrader, 1. If you go to the Edgerater website Blog page and search for this blog(just search on the word "simple") "A Simple Long Term Timing Signal For The Markets: BackTest" he explains a quick and dirty script, with how to get entries and Exits and then run the backtest which he calls 'Trade Simulations'. 2. He also has some old videos on his Edgerater Youtube channel that cover running simulations in more depth. and of course there will be an explanation coming up when he finishes his 4 part video series he's currently working on. 3. To give everyone an idea of the complexity level of the Edgerater scripting language here is a script for the standard MACD with Histogram: MACD : EMA(CLOSE,12) - EMA(CLOSE,26); SIG : EMA(MACD,9); HIST : (MACD-SIG), COLORSTICK; Ed S. |

12/23/2020 1:11:00 PM Below is a SF filter from a 2016 post in · Filter Exchange · Breakout Trading Filter - GREAT RESULTS! followed by an Edgerater Chart Script I wrote to emulate the filter in Edgerater Pro and to also backtest it. This is a more complex comparison of the 2 filter code languages. Note: I tried to keep variable names common between the 2 programs. Questions are welcome, Ed S. Here's the Edgerater Script/Filter: cond1: BETWEEN(c,.25,12); cond2: c > ref(HHV(c,80),1); cond3: c > open; fif: count(high == low,60); cond4: fif < 15; xmsum:= ema(c,200) + ma(c,200); xema_avg:= xmsum / 2; matop5: max(MA(c,400), xema_avg); mabot5: min(MA(c,400), xema_avg); v1a: count(matop5 < 1.25 * mabot5, 80); v2a: count (ref(matop5,80) < 1.25 *ref(mabot5,80), 80); v4a: v1a + v2a; v5a: 80 + v4a; cond5: v5a == 240; matop6: max(MA(c,80), xema_avg); mabot6: min(MA(c,80), xema_avg); v1b: count(matop6 < 1.15 * mabot6, 80); v2b: count (ref(matop6,80) < 1.15 *ref(mabot6,80), 80); v4b: v1b + v2b; v5b: 80 + v4b; cond6: v5b == 240; event: cond1 & cond2 & cond3 & cond4 & cond5 & cond6 |

12/24/2020 6:13:02 PM @ Ed Merry Christmas to you and all members who celebrate. THANK YOU for re-posting a great "Breakout Trading Filter - GREAT RESULTS!". I agree with Wilson that paying more for an advanced sub to see all features from the above filter might be well worth it. For now, I will just have to ask you questions based on my incomplete view of the filter. At the end of Dec 23, 2020 trading day, I was able to find IWM, which has var5a=240 and var5b=240, and the filter does indeed appear to be great at finding breakouts. But by the time. a pics finally appears from var5a=240 and var5b=240, it seems like the bull run is probably pretty long in the tooth, and using other filters like snappyfrog's systems, that pick would be more likely to drop next or pull back. So, is the above filter condition var5a=240 and var5b=240 just to show backtest examples of breakouts after the facts? Do you have any suggestions for us to capitalize on the running up to the breakouts ? If the answers were already covered in the aforementioned thread, please kindly refer me to the specific posts or paragraphs. Thanks again. |

12/25/2020 5:30:38 PM @cheese, 1. When I run that filter on Dec 23 it does not return IWM even when I increase the price range. 2. No that filter was not designed as a backtest filter by Wilson, as he introduced it as a filter he had been using for the prior year, and had made about $32K paper trading in his $50K margin account. Though if you read all of his posts in that old thread you can see he varied his trade methodology quite a bit... 3. Looking at the charts it appears that a lot of the run ups prior to the "breakout result day" occur after a considerable period of the Close 80 day high being horizontal for many bars, so perhaps playing around with that might work. I never used the filter for trading, it was kind of my first test to see how hard it would be for me to backtest SF filter code by converting it to Edgerater script (I was pretty new to SF back then). 4. My backtest showed the filter being a little better than 50% winners for the prior year back then which coupled with many undefined trading rules led me to not pursue it much further. Ed S. |
