8/20/2010 2:07:23 AM The "Death Cross" is when the 50-day moving average crosses below the 200-day moving average of a major index. I'm not sure if that typically applies to the major barometer Dow 30 or SP 500 index. Anyway, in a newsletter I read tonight, its "Death Cross" favors the Exponential Moving Average (vs. the Simple Moving Average). It also favors the Dow 30. Here is a script I wrote that calculates both the Simple MA and Exponential of the Dow, SP 500, QQQQ, and VTI (I use DIA for the Dow, and SPY for SP 500): I would like to have the SMA-cross and EMA-cross columns to include 3 places to the right of the decimal, In other words (e.g.,) DIA on 8/19/10 would show as 1.011....not 1.01 as it now shows. I have my reasons. The newsletter says, in essence, if the Dow 30 EMA "Death Cross" occurs......it will be the last nail in the bearish coffin. According to the above script, here are 8/19/10 results of the EMA crossovers: SPY, 1.00 QQQQ, 1.02 DIA, 1.01 VTI, 1.00 I would like to change the script so I can get the results to show 3 places to the right of the decimal point, using SF's new "rounded" feature, or alternate way (preferably using the "rounded" feature). Can someone help? Thanks. |

8/20/2010 3:24:01 AM ..just a suggestion: try using EMA(50) crossing SMA(200).. |

8/20/2010 8:52:39 AM Mystiq, Your idea may be right on target. I was just following the newsletter writer's pick on using the Dow 50-day (EMA) cross below the Dow 200-day(EMA) figure. Still trying to figure out how to get 3 places to the right of the decimal figure. Anybody with an idea how to do this (preferably using SF's 'rounded' feature, if that's possible)? Thanks, again! In the meantime, mystiq, why do you suggest using the EMA for the 50-day and SMA on 200-day figure? |

8/21/2010 2:25:31 AM In the meantime, mystiq, why do you suggest using the EMA for the 50-day and SMA on 200-day figure? EMA represent the fast line and SMA the slow line. For spotting early moves AND ...less false moves. |

8/21/2010 8:51:33 PM mystiq, I said, "In the meantime, mystiq, why do you suggest using the EMA for the 50-day and SMA on 200-day figure? You replied: "EMA represents the fast line and SMA the slow line. For spotting early moves AND ...less false moves." ---------------------------------------------------------- I can certainly see your first point at times (early moves), but can you elaborate on your second point (less false moves)? Not sure why the latter would be true. Please...share your thoughts. I'm always open to constructive input! As you know, dividing EMA(50) by MA(200) is easily doable. For actual numbers, at end-of-day on Friday, Aug. 20, here are comparative numbers on the ETF, SPY (SP 500): Less than 1.00 (i.e., .99 or lower) would represent the so-called "Death Cross" has taken place: MA(50) / MA(200) = 109.11 / 111.88 = .9752 (rounded .98) EMA(50) / MA(200) = 109.88 / 111.88 = .9821 (rounded .98) EMA(50) / EMA(200) = 109.88 / 109.76 = 1.0011 (rounded 1.00) Note: I prefer the non-rounded number for more precision. That is fixable, thanks to the suggestion earlier! The article I read 2 days ago, said the writer preferred using strictly the EMA crossover. Don't know if that is just his opinion, or conventional wisdom. I had always thought the Death Cross was based on the crossover of the Simple Moving Average (MA). But maybe the hybrid of EMA(50) / MA(200) makes the most sense. Anyway, from the numbers above, we're "dying" on the first two numbers, and just hanging by a thread on the strictly EMA (the third one) crossover. At least with SPY. Additional comments from anyone? |

8/22/2010 12:29:02 AM Here is the update I made to my original script. I changed the % column to effectively get a 4-figure to the right of the decimal (thanks to the suggestion), by multiplying by 100. Thus, instead of the previous answer showing (e.g.,) .98, it now shows as 97.52. In other words, 97.52%. That would be the same as .9752 that I originally sought. I also added these columns: WMA(30), RSI(14) and MACD(12,26). Does anyone have any other suggestions for indicators to include? |

8/23/2010 12:59:05 AM update I made to my original script. I changed the % column to effectively get a 4-figure to the right of the decimal (thanks to the suggestion), by multiplying by 100.

I also added these columns: WMA(30), RSI(14) and MACD(12,26). Does anyone have any other suggestions for indicators to include? try using IFT() - because 50ma could be just using 200ma for support and could bounce or represent a false breakdown. IFT() would confirm whether a new trend is starting or continued falling. I suggested ema/sma only because I adapted the combination from ema2/sma3 to signify a new trend might start/end. Less false moves because 200sma will not whipsaw or move as fast as 200ema. |

8/23/2010 9:13:06 AM Mystiq, You said I should try using IFT(). Now that's a new one to me. So I had to look it up in the SF Manual, page 64. I feel like a kindergartner hanging out with 3rd graders in school. I haven't even passed SF 101, and you want me to jump to SF 301....? Just kidding, of course. I certainly admire you and others for your scripting expertise. That said, om page 64, SF uses the example of IFT(5,9). First number is the RSI days, the second number is the weighted MA days [not EMA]. 5,9 seem short, considering I'm using your suggested script line in conjunction with 50-day and 200-day numbers for the so-called Death Cross. In light of what I just said, would you still use IFT(5,9) or other numbers? Zack |
