DMI (Directional Movement Index) Format, Label, Watchlist, Scan for ThinkorSwim

[flowtrader]

The DMI indicator (Directional Movement Index) will tell you which direction the price of a stock is moving. When the +DI line is above the -DI line, it means there is more upward movement than downward and vice versa.

The way I use the DMI is a bit different. Instead of using this indicator to tell bullish or bearish trend, I use it as a sideways detector. When the two lines are moving next to each other, it's telling me that the market is choppy at the moment.

Here is an example on the $BYND chart:

The DMI indicator is available right inside ThinkorSwim. You can just add it without additional code. To make things a bit easier on my part, I asked @WalkingBallista if it was possible to make a Watchlist column that displays the range between the DMI lines. The closer they are to each other the more likely that the stock isn't moving anywhere. And of course, he said yes.

Here is the DMI Range watchlist column for anyone interested.

thinkScript Code

# WalkingBallista DMI Range
# https://usethinkscript.com/d/193-dmi-directional-movement-index-watchlist-for-thinkorswim

input length = 14;
input averageType = AverageType.WILDERS;

def hiDiff = high - high[1];
def loDiff = low[1] - low;

def plusDM = if hiDiff > loDiff and hiDiff > 0 then hiDiff else 0;
def minusDM =  if loDiff > hiDiff and loDiff > 0 then loDiff else 0;

def ATR = MovingAverage(averageType, TrueRange(high, close, low), length);
def "DI+" = 100 * MovingAverage(averageType, plusDM, length) / ATR;
def "DI-" = 100 * MovingAverage(averageType, minusDM, length) / ATR;

plot range = AbsValue(AbsValue("DI+")-AbsValue("DI-"));

is there any way to create a color coded watchlist column? green for DMI up and red for DMI down? DMI only not ADX combo

Hey there!

Ive been beating my head against the wall on some simple *** issue, and had given up all hope...and then I remembered this site that is full of coding geniuses who are glad to help us dumb shits out with the technicals... pretty straight forward, Im looking to AddCloud to the DMI...green in between when D+ is over D-, and red in between when D+ is under D-... here is what i got so far but Im getting error after error....Thanks a ton to whomever feels generous enough to situate this for me...

declare lower;


input length = 14;
input averageType = AverageType.WILDERS;

def hiDiff = high - high[1];
def loDiff = low[1] - low;

def plusDM = if hiDiff > loDiff and hiDiff > 0 then hiDiff else 0;
def minusDM = if loDiff > hiDiff and loDiff > 0 then loDiff else 0;

def ATR = MovingAverage(averageType, TrueRange(high, close, low), length);
plot "DI+" = 100 * MovingAverage(averageType, plusDM, length) / ATR;
plot "DI-" = 100 * MovingAverage(averageType, minusDM, length) / ATR;

def DX = if ("DI+" + "DI-" > 0) then 100 * AbsValue("DI+" - "DI-") / ("DI+" + "DI-") else 0;
plot ADX = MovingAverage(averageType, DX, length);


"DI+".SetDefaultColor(GetColor(1));
"DI-".SetDefaultColor(GetColor(8));
ADX.SetDefaultColor(GetColor(5));

plot "D+" = close;
plot "D-" = close(10);
AddCloud ("D+", "D-" , Color.GREEN, Color.RED);

You shouldn't define variables as a string. It said (plot "D+" = close; && plot "D-" = close(10) were already defined. I deleted, seemed to work

 

[LGLyon]

Is it possible or is there a code for a DMI label that measures the difference between the DMI+ and the DMI- readings?

 

[JoeDV]

This what you mean?

def DMIPlus = DMI(14,"Wilders")."DI+";
def DMINeg = DMI(14,"Wilders")."DI-";
def DMIDiff = DMIPlus - DMINeg;

AddLabel(1, "DMI Diff is "+ DMIDiff, if DMIDiff > 0 then color.green else if DMIDiff < 0 then color.red else color.gray);

Hi guys,

Think this is my first post after lurking for a long time. thanks for being here and everything y'all post!

I am trying to clean up and fix whats not working in my below code -

Issues:
1 - When DI+ is above or below Over Sold or Over Bought I have Upsignal and Downsignal arrows, but I Truly only want an arrow when the DI+ is extended beyond the over bought value and reversing lower then the previous closed DI+ value in the last candle to have an arrow, not a bunch of arrows. Vice versa issue for Over bought, I am trying to get only 1 arrow to show when the DI+ is reversing and beyond the Over Sold value line and now reversing higher then the previous DI+ value to have an arrow close in that candle time frame.

2. My chart alerts are not going off when an arrow is showing! If anyone can fix my chart alert code to go off when an arrow is showing, I'd appreciate it.

3. DI+ Bullish and bearish Divergences. I would love to be able to see DI+ Divergences. Bullish Divergence when The stock price having found a previous low, went up and now creating a new lower low, but the DI+ is showing and closing higher then DI+ found at previous low.
Bearish divergences when the stock price had a high, went down, and now creating a new high. It would be nice to see DI+ Divergences when the DI+ is now lower at the new high then what it was when stock price was previous high.

Alot to ask, but I can provide coffee as needed! Thank you so much for even reading this!

I posted my example of divergences to explain myself better in red lines. and my terrible arrows that need help fixing so they dont repeat!

declare lower;

input length = 14;
input averageType = AverageType.WILDERS;
input over_Sold = 15;
input over_Bought = 70;

plot oversold = over_Sold;
plot overbought = over_Bought;

def hiDiff = high - high[1];
def loDiff = low[1] - low;


def plusDM = if hiDiff > loDiff and hiDiff > 0 then hiDiff else 0;
def minusDM =  if loDiff > hiDiff and loDiff > 0 then loDiff else 0;

def ATR = MovingAverage(averageType, TrueRange(high, close, low), length);
plot "DI+" = 100 * MovingAverage(averageType, plusDM, length) / ATR;
plot "DI-" = 100 * MovingAverage(averageType, minusDM, length) / ATR;

def DX = if ("DI+" + "DI-" > 0) then 100 * AbsValue("DI+" - "DI-") / ("DI+" + "DI-") else 0;
plot ADX = MovingAverage(averageType, DX, length);

"DI+".SetDefaultColor(GetColor(1));
"DI-".SetDefaultColor(GetColor(8));
ADX.SetDefaultColor(GetColor(5));

plot UpSignal = if "DI+" < over_Sold then "DI+" else Double.NaN;
plot DownSignal = if "DI+" > over_bought then "DI+" else Double.NaN;

UpSignal.SetDefaultColor(Color.UPTICK);
UpSignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
DownSignal.SetDefaultColor(Color.DOWNTICK);
DownSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

Alert((UpSignal) or (DownSignal), GetSymbol() + "DI+ Alert", Alert.BAR, Sound.Ring);

refine the DI+ from the DMI TOS default indicator.

my terrible arrows that need help fixing so they dont repeat!

Not sure what you are asking.
Your question is how to print only one arrow? And the one arrow needs to be the last arrow?

Replace your arrow plots with:

plot UpSignal = if "DI+"[1]  crosses above over_Sold and  then "DI+" else Double.NaN;
plot DownSignal = if "DI+" crosses below over_bought then "DI+" else Double.NaN;

Hi all,
I am asking if one of you code masters could modify the TOS DMI indicator for me. What I want is a marker (of some sort) on the price chart when the DI+ DI- lines cross. The screenshot gives you an idea of what I am asking for. An alert would be helpful too, but don't want to take advantage of anyone.

thanks in advance...
