These are the archived posts for the RSI. The current thread can be found:


This indicator for ThinkorSwim will help you detect bullish and bearish RSI divergences on your chart.
The header of this script also detailed how to set up the scanner that looks for RSI divergences, which often signal possible reversals.
There are a couple of versions for you to check out. The first by Mobius, the other by @cos251

thinkScript Code

Rich (BB code):
# RSI_With_Divergence
# Mobius
# V01.01.2013
# 4.15.2019
#hint:<b>RSI with Divergence</b>

# Note: Install this as a new study. Save this study using the name above (the first line of code RSI_With_Divergence).

# To use this study as a scan; DO NOT TRY TO LOAD IT DIRECTLY IN THE SCANNER, IT WILL THROW AN ERROR MESSAGE. Go to the scan tab. Delete any existing scan criteria. Click Add Study Filter. Click the window under Criteria. In that drop down menu click Custom. Delete the existing study. Click Add Condition. Click the down arrow in the Select A Condition window. Click Study. Scroll down the List till you find RSI_With_Divergence and click it. Click on the Plot window and you can choose Dhigh or Dlow in addition to the default plot RSI. If you choose either of the divergence siganls choose is True from the center column. Click on the aggregation period at the top left and set the aggregation period you want scaned. Then click Save and when the popup window shows the warning that this is a custom scan chose OK. Now put the list of stocks you wish to scan in the Scan In box and chose any list you want that to intersect with. If you wish to make this a Dynamic WatchList, save this scan with a name such as RSI_With_Div_WL then in your Gadgets box click the little gear icon, locate the name of the scan you just saved and click it. As equities match the scan criteria they will populate the list.

UPPER STUDY VERSION 1.0 (per request from @TradeUp)
This is the upper version as requested (pretty lean on code too).
For now only includes the candle coloring, will have to work on plotting the Divergence Lines.

Scan on daily bars is not displaying the results though study when plotted on the chart shows there is RSI Divergence....anything wrong with this search iam doing...
 
Trying to set a custom scan, but the explanation in the code doesn't agree with the actual variables used.

1) Text mentions Dhigh and Dlow, while under Plot you get PlotHline, pivotLow, PivotDot.

2) Within how many bars?

Should I use the info under MACD Divergence?

MACD Divergence Scanner

Bullish
MACD_Divergence_2019()."pivotLow" is true within 6 bars
Bearish
MACD_Divergence_2019()."PlotHline" is true within 6 bars

Hello, How can i change the moving Exp Moving average to Wilders for the divergence?
@Trading51 Mobius makes Proprietary indicators for Money Managers and Hedge Funds among others.
If he put an Exponential MA in there, then there is a very good reason for it.
If you feel you must change it, Type Universe in the Search Bar above and you'll find links and examples of how to make changes.
Good trading!

Also, please fill out your signature so that we know more of your point of view. Thanks! :)

coding can be difficult but if you play around with it these small ADJUSTMENTS ARE EASY AND MAKE GOOD PRACTICES,, CHEERS MATE, sorry for the caps LOL
 
I set up a scan query on this but it returns nothing... Does anyone have any idea why?

The scan query condition:

RSI_Divergence()."PlotHline" is true within 3 bars

The odd thing that it starts working at "within 7 bars" and higher. Same goes if you substitute "pivotLow" for "PlotHline".

Very hard to say without knowing the list you scan in, time frame and other particulars. Please provide more information. There is nothing wrong with the code. Hopefully someone can help you as I will be in and out for a while.
 
Oh, sorry, it's really ordinary: daily time frame, scanning all stocks. With no other conditions. I thought maybe there's something in the code preventing using this condition for less than "within 7 bars"? It seems strange that there would be hundreds of hits for "within 7 bars" and zero for "within 6 bars".

Hi! Just joined the website and have greatly enjoyed reading through all of the discussions and studies available - fantastic website. I just had a quick question regarding the RSI divergence indicator above. The divergence line (dotted) will appear at the close of the next candle, otherwise, the candle following the most recent high or low, correct? Also, if a new low or high is created afterward, the line will be replaced, right? Thank you in advance for your help - have a great weekend!
 
@NS78-TOS Hey, that's correct. The divergences are slightly delayed due to waiting for confirmation from the candles. I have not used this in a while so I can't answer the second question, but I would assume that is the case.
 
I realize this might be tricky but is there any way to amend this indicator to show past divergences? Right now, the indicator only shows the most recent bullish and bearish divergences but if this could be changed to show all past divergences either in the same window or even on the chart itself via arrows/etc., that would be phenomenal to back-test this tool with other strategies. Just an idea... thanks for your consideration! ;-)
