Despite being developed before the computer age, Wilder's indicators are incredibly detailed in their calculation and have stood the test of time. Directional movement is calculated by comparing the difference between two consecutive lows with the difference between their respective highs.
Directional movement is positive plus when the current high minus the prior high is greater than the prior low minus the current low. A negative value would simply be entered as zero. Directional movement is negative minus when the prior low minus the current low is greater than the current high minus the prior high.
This so-called Minus Directional Movement -DM equals the prior low minus the current low, provided it is positive. The chart above shows four calculation examples for directional movement.
The third pairing shows a big difference between the lows for a strong Minus Directional Movement -DM. The final pairing shows an inside day, which amounts to no directional movement zero.
All inside days will have zero directional movement. Basically, ATR is Wilder's version of the two-period trading range. The calculation example below is based on a period indicator setting, as recommended by Wilder.
Above is a spreadsheet example with all the calculations involved. There is a day calculation gap because approximately periods are required to absorb the smoothing techniques. Because of Wilder's smoothing techniques, it can take around periods of data to get true ADX values. ADX values using only 30 periods of historical data will not match ADX values using periods of historical data. ADX values with days or more of data will remain consistent.
As with an exponential moving average , the calculation has to start somewhere so the first value is simply the sum of the first 14 periods. As shown below, smoothing starts with the second period calculation and continues throughout. First, calculate an average for the first 14 days as a starting point.
The second and subsequent calculations use the smoothing technique below:. Crosses of these directional indicators can be combined with ADX for a complete trading system. Before looking at some signals with examples, keep in mind that Wilder was a commodity and currency trader. The examples in his books are based on these instruments, not stocks.
This does not mean his indicators cannot be used with stocks. Some stocks have price characteristics similar to commodities, which tend to be more volatile with short and strong trends.
Stocks with low volatility may not generate signals based on Wilder's parameters. Chartists will likely need to adjust the indicator settings or the signal parameters according to the characteristics of the security. This determination helps traders choose between a trend-following system or a non-trend-following system. Wilder suggests that a strong trend is present when ADX is above 25 and no trend is present when below If you want to adjust up the power, the module will need to be connected to a heat sink or fan as shown in this application note download.
Downeast Microwave linear amplifiers can also be added to our TX Over the years we have gone back and forth between having available a transceiver or a transmitter that would pair up with a downconverter. The demand has always been about So now, since new TV's have analog cable tuners built in, we went back to stand alone transmitters. Also, you may not need a transceiver, downconverter or TV to use at the transmit location at a public service event.
Some areas may only operate through a crossband repeater and very little simplex. Separate units also offer a lower entry cost to 70cm ATV since a cable ready TV can be used to receive on the 70cm ham band. If you do, and it does not come with a manual, email us requesting one giving model number and any revision letter or date etched on the exciter board inside - always include your call letters when emailing us.
If you need trouble shooting advice, contact us with your questions. See our repair policy. They are one of the best designed high gain and broadband beams for ATV. With this antenna, 4 Watts is plenty for most all line of sight applications. The hard part, however, is getting line of sight between the two antennas given the curvature of the earth, trees, buildings, etc. For temperature inversion tropo skip usually in early summer, you can often get over the horizon snow free DX of 60 miles and even further with an added amp, or some snow in the video decreasing one P unit for each doubling of distance.
For portable Emcomm, public service work or if antenna size is limited for what ever reason, we also have the The Olde Antenna Lab 5 element 5Lcm beam as shown at right that gives 8 dBd on a 31 inch boom.
The 10 element 10Lcm gives 11 dBd on a 62 inch boom. Also see Homebrew Antennas. Note that even with home made ground planes at each end running 4 Watts the snow free DX is over 2 miles. Low loss coax cable and properly made connectors are also important. N plugs have a gasget that will keep water from getting inside the shield and ruining the coax.
If you dont want to put on your own plugs, places like RF Parts , Cable X-Perts , and others can supply various lengths with connectors ready to go. Good antennas up high as possible and line of sight are the most important part of any ATV system for best DX. End mounted horizontal or vertical Video out is usually a yellow RCA phono plug which goes into the transmitter video jack.
Your camcorder may have two audio plugs if stereo - connect the red right audio out plug into the transmitter line audio jack. However, it may be preferable to use a video camera which will run continuously and dedicate it to the station if your camcorder has a battery saver which shuts it off if not recording after minutes.

I'm a fairly new trader that started last year and a few months back I found your videos and only recently became a member to the site.
I still have lots and lots to learn!
