FW_DPO_MOBO Script

Hey everyone,

I've been utilizing the FW_DPO_MOBO Indicator and I would like to code it into one of my strategies. The problem is that when you go to copy and paste the script to implement it into a strategy, the script says "Source code isn't available." The TTM_Squeeze Indicator has this same problem, but I've seen reiterations of the script to make it the same as the original indicator. I was wondering if anyone has the script for the FW_DPO_MOBO Indicator that is editable and able to be coded into a strategy. I know it is a combination of Bollinger Bands and the Detrended Price Oscillator, but the original indicator somehow scales the Bollinger Bands in a special way for the Detrended Price Oscillator to work better with it. I will post the code for the FW_DPO_MOBO so you can see what I am talking about.

Any help would be much appreciated!


Code: 
#
# TD Ameritrade IP Company, Inc. (c) 2010-2020
#
# Source code isn't available.

declare lower;

input price = CLOSE;
input colorNormLength = 3;
input dpoLength = 14;
input moboDisplace = 0;
input moboLength = 10;
input numDevDn = -0.8;
input numDevUp = 0.8;
input coloredMobo = Yes;
input coloredFill = Yes;
input breakArrows = Yes;
input moboShowMid = No;

plot DPO = Double.NaN;
plot MidlineP = Double.NaN;
plot UpperBandP = Double.NaN;
plot LowerBandP = Double.NaN;
plot Zeroline = Double.NaN;
plot BreakOutArrow = Double.NaN;
plot BreakDownArrow = Double.NaN;

Just remember that you need to reference the FW_DPO_MOBO for every plot you want to use... I have my own custom versions and have posted my short version below... Note that my settings differ from the original release...

Ruby: 
#My_FW_DPO_MOBO
#Based on TOS FW_DPO_MOBO
#Modified for personal use by rad14733

declare lower;

input price = HL2;
input colorNormLength = 3;
input dpoLength = 13;
input moboDisplace = 0;
input moboLength = 13;
input numDevDn = -1.0;
input numDevUp = 1.0;
input coloredMobo = Yes;
input coloredFill = Yes;
input breakArrows = Yes;
input moboShowMid = Yes;

#plot DPO = Double.NaN;
plot DPO = FW_DPO_MOBO(price, colorNormLength, dpoLength...

@BBDPDC @rad14733 I am currently using the script that you have shared...
What I would like to is also to configure a scan to pick up signals when
1. The middle line change from Red to Green or Green to Red but it doesn't seem to have the conditions to configure the scan
Alternative, i also tried to scan using the "DPO line to cross above the Centerline" but i cant add another condition for it to only show signals that are below the zeroline?

May I know if you have manage to scan signals when the middle line changes from Red to Green or vice versa? Or how can add a condition to only displays signals Only when it is below the Zeroline?

@BBDPDC May I also request if you can share your script that shows how the labels are plotted on your moving average?

Thank you very much

@Nick Unfortunately i have limited coding experience and mixed with little time and a wealth of other available material just on this site, I've actually excluded this indicator and the changes i made as the signals appear unreliable using my version (too many and late).

As for the MA labels on the upper i posted, those are the Hull Concavity indicator which i slightly adjusted to shrink the bubble and took all the arrows out.....it looks back so can fire and disappear until the following candle after the signal has closed but is incredibly reliable in determining an uptrend. Set to 21 on a 1m chart. Take a look here https://usethinkscript.com/threads/...ng-points-and-concavity-2nd-derivatives.1803/

DPO weekly timeframe

Hi, i have tried to modify the FW_DPO_MOBO script to fit into upper study to plot the signals in the script below. I am using a WEEKLY chart. The purpose of this plot is to identify the downtrend momentum of the stocks has slowed down then goes sideway before it resumes it uptrend.
Usually when all the plot conditions are met, the Arrow will appear on the same candle. From the attached pic, I observed that this does not happen all the time, and like to know
1. Is there anything wrong with my plot?
2. How can I set the arrow to be plotted on the same candle when the conditions are met?
3. Does the DPO line measure the Momentum of the stock?? If I like to increase the sensitivity of the DPO line, ie the DPO cuts the midline shortest time, should I decrease the DPO Length or the MOBO_length??
4. Any other suggestions are greatly appreciated.

Thank you

  • I have never had TOS plot on the same candle. The condition occurs and triggers an arrow on the next candle (except maybe? repainting indicators)
  • The technical definition states that DPO does not measure momentum:
What Is a Detrended Price Oscillator (DPO)?
Basically, it strips out price trends in an effort to estimate the length of price cycles from peak to peak or trough to trough.

Unlike other oscillators, such as the stochastic or moving average convergence divergence (MACD), the DPO is not a momentum indicator. It instead highlights peaks and troughs in price, which are used to estimate buy and sell points in line with the historical cycle. ~Investopedia
Click to expand...

But when compared to the MACD, it looks very similar. So if it walks like a duck... sounds like a duck?

Suggestions:
I don't use TOS Fw DPO Mobo. I use the one here from @rad14733: https://usethinkscript.com/threads/fw_dpo_mobo-script.4771/#post-44180. He does use different lengths.
This indicator appears on most of my charts. I buy dips and then look for reversals.
I am not a fan of arrows, especially w/ oscillators, especially w/ this particular script. For me, it is more about how the oscillator is lining up with your other three non-collinear indicators on your three timeframes.

All that said, your arrows appear to be working. I kind-a like them.

If you're not happy with email, and don't mind registering (free I think -- my credentials are still good YEARS later), you can download the thinkscript code from the firstwave website here:

There is this one and a bunch more. I always liked the ADX Fuel Cells myself.

Hi Mashume,

Do you know if the FW_MMG or FW_FisherTransformer indicators can be found anywhere? These are the two that are not included on the FW website.

Best,
Mitch

Hey all,
I really enjoying on demand trading with FW_DPO_mobo, those arrows and the cloud changing from green to red is very helpful, but I don't have time to sit and watch my 2 hour candles all day. Is there any way to create an alert with the thinkScript on the mobo indicator when the arrow changes from up to down or vice versa? I'm at a loss.

Any help would be greatly appreciated.

Sorry. Guilty of posting an image w/o a chart link. 😵 Must have been something I was working on in passing.
I don't have it anymore. Thanks for the heads up, I deleted the image.

I agree. No arrows. This uses a ToS built-in indicator that is copyright-protected.
We can't see the code, so can't see what changed.
You can try contacting Support.
Do come back and tell us what they say.

This information about how to use MoBo indicator to long or short the market is from Tradingview. "This indicator is the Mobo Bands (Momentum Breakout Bands). These bands are bollinger bands that have an adjusted standard deviation. There are Buy signals when it has momentum breakouts above the bands for moves to the upside and Sell signals when it has momentum breakouts below the bands for moves to the downside. The bands simply suggest that all markets have periods of chop which we all know to be true. While the price is inside the bands it is said to be trendless. Once the breakouts happen you can take trades in the breakout direction."

first reply: I see what you mean, I'm not getting those arrows either. I'm going to reach out to my team to see if this was a recent update or if we can get more clarification.
second:

this link goes over the FW_DPO_MOBO study which would show those arrows I just found
