Awesome Oscillator (AO) (Last upd: Apr, 13 2010)
admin · Tue Oct 20, 2009 2:56 pm
DESCRIPTION:
Awesome Oscillator (AO) is the difference between the 34 period and 5 period simple moving averages of the candle’s/ bar’s middle points. Basically: (High+Low) / 2.
AO Indicator calculates and determines market momentum at a given time when comparing the last five bars to last thirty four bars.
Awesome Oscillator (AO) is displayed on the chart as a histogram. Awesome Oscillator can present us with three buy signals and also three sell signals, but its not recommended to use them until the first fractal buy or sell signal is triggered outside the Alligator’s mouth.
CALCULATION:
MEDIAN = (HIGH+LOW)/2 AO = MVA(MEDIAN, 5) - MVA(MEDIAN, 34)
SCREENSHOT:
Download indicator (New version):
Apr, 13 2010, ng: In the new version of the indicator: 1) By default the covering line is not shown. An additional parameter is added to show the covering line (It may be useful for applying indicator on the AO results or for using the indicators in another indicator).
2) In case the bar has the same size as the previous bar, the bar will have the same color (in the previous version the equal bar was always green).
Code: Select all `function Init() indicator:name(“Awesome Oscillator”); indicator:description(“”); indicator:requiredSource(core.Bar); indicator:type(core.Oscillator);
indicator.parameters:addInteger(“FM”, “Fast Moving Average”, “The number of periods to calculate the fast moving average of the median price”, 5, 2, 10000); indicator.parameters:addInteger(“SM”, “Slow Moving Average”, “The number of periods to calculate the slow moving average of the median price”, 35, 2, 10000); indicator.parameters:addBoolean(“SC”, “Show the covering line”, “Shows line trough the tops of bars”, false); indicator.parameters:addColor(“CL_color”, “Color for covering line”, “Color for covering line”, core.rgb(255, 255, 255)); indicator.parameters:addColor(“GO_color”, “Color for higher bars”, “Color for higher bars”, core.rgb(0, 255, 0)); indicator.parameters:addColor(“RO_color”, “Color for lower bars”, “Color for lower bars”, core.rgb(255, 0, 0)); end

function Update(period, mode) MEDIAN[period] = (source.high[period] + source.low[period]) / 2; FMVA:update(mode); SMVA:update(mode);
if (period >= first) then CL[period] = FMVA.DATA[period] - SMVA.DATA[period]; end if (period >= first + 1) then if (CL[period] > CL[period - 1]) then GO[period] = CL[period]; elseif (CL[period] < CL[period - 1]) then RO[period] = CL[period]; elseif GO[period - 1] > 0 then GO[period] = CL[period]; else RO[period] = CL[period]; end end end`

Can this be made into a signal? Personally, I’m interested in zero-line crossing, but any other parameters are welcome.
Thanks!

I, too, would be very interested in either this indicator or the Elliott Wave Oscillator (EWO) as a signal, with the zero line cross (i.e., red to green or vice versa).

How to read/use the heat map?
Re: Awesome Oscillator (AO) (Last upd: Apr, 13 2010)
pawelas · Tue Sep 21, 2010 6:04 pm
heat map doesn’t work correctly in all indicators because it doesn’t update each tick, only at the beginning of the candle, so if during this candle price dramatically, heat map stays the same. Even bigger problem is for higher time frames because output has to be updated for the highest time frame number of periods on your chart. I pointed out this problem before but so far it wasn’t resolved.

Is it possible to have the “custom signals” automatically generate and execute buy/sell orders? Or, like in the case of the AO signal, a signal is just to show on the chart how the strategy would have worked?

AO multi-timeframe heat map is updated, in order it could work with the new version of platform.

New version “AO_Heat_Map2.lua” with improved performance was added. Indicator uses different visualization method, so I add it as a separate indicator. Please use it with newer versions of platform.

Can we please request an amendment to the Awesome Oscillator indicator.
I would like to plot a Signal line which is a moving average of the difference between Slow and Fast Lengths. Signal line would be created using “Averages Indicator” assortment of moving averages depending on user preference. Ideally the Signal line would change color when slope changes just like Averages Indicator.
calculation for Signal line : (Slow length-Fast length)/2
example of settings: Awesome Oscillator with Signal Slow=30, Fast=4, Signal=13
This Signal line serves the purpose of highlighting 1.) heavy price action pressure created when gap is created between AO slope change and Signal line 2.) Identify tops/bottoms of waves when AO slope change and Signal line slope change converge. 3.) Divergence between overall slope trend and singular price bar.
I would also like an Alert function added to this amendment. Alert function would be based solely on Signal line slope change.
((Question to development team: Is it possible for Alert to be created when AO histogram value CROSSES Signal line value?))
Please see attached image for illustration pertaining to this request.
Thanks!
