Fun with ThinkScript

BTW, is there any script that would show on the chart (e.g. top right corner ) P/L status on the open position?

Can I turn this indicator into a strategy

This should be a fairly simple request:

The thinkscript below adds a horizontal line on the chart to mark last week's closing price. Can anyone please tell me how to make an addition where I can have a visible text label above the horizontal line to say "LWC"? Thanks a million in advance.

----------------------------------------------------------------------------------------

declare upper;

def Today = if GetLastDay() == GetDay() then 1 else 0;
def DrawHighs = if (close < high(period="Week" )[1] AND close > low(period="Week" )[1]) OR high(period="Week" ) > high(period="Week" )[1] then 1 else 0;
def DrawLows = if (close < high(period="Week" )[1] AND close > low(period="Week" )[1]) OR low(period="Week" ) < low(period="Week" )[1] then 1 else 0;

plot yClose = if Today then close(period = "Week" )[1] else Double.NaN;
yClose.SetDefaultColor(Color.LIGHT_GRAY);
yClose.SetLineWeight(1);
yClose.SetStyle(Curve.MEDIUM_DASH);

Robert, What color swatches (numbers) are you using for your chart color? I like it, but am unable to match it. Thank you

Ok fellow traders...been a while since I've posted but I have a code that was done for Ambibroker (AFL) that I'd like to get coded for TOS...

The code basically highlights on the chart when the Bollinger Bands are in a Squeeze...so those of you that use the BB squeeze as a trade strategy may find this helpful.. See pic of chart here - [s21.postimg.org]

If anyone can help code it for TOS it would be greatly appreciated!

The Ambibroker Code is below:

Length = 14;
Price = EMA(Close, Length);
  
// Keltner
kLength = Length;
kN = 1.5;
kATR = ATR(kLength);
kUpper = Price + kN * kATR;
kLower = Price - kN * kATR;
  
// Bollinger
bbLength = Length;
bbN = 2;
bbStDevValues = StDev(Close, bbLength);
bbUpper = Price + bbN * bbStDevValues;
bbLower = Price - bbN * bbStDevValues;
  
IsBBSqueeze = bbUpper <= kUpper AND bbLower >= kLower;
 
Proportion = (kUpper - kLower) / (bbUpper - bbLower);
BBBreakout = Cross(1,Proportion);
Periods = Param("BBPeriods", 14, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style";
bbtop=BBandTop( C, Periods, Width );
bbbot=BBandBot( C, Periods, Width );
Plot(bbtop, "", Color, Style );
Plot(bbbot , "", Color, Style );
 
sqeezcolor=ColorRGB(194,220,218);
 
PlotOHLC( bbtop,bbtop, bbbot,bbbot, "",IIf(IsBBSqueeze,colorYellow,colorWhite), styleCloud|styleNoRescale,  Null, Null, Null, -1 );
Plot(Close,"Close",colorGreen,styleCandle);
 
Filter = BBBreakout;
 
AddColumn(BBBreakout, "BB Breakout", 1, colorWhite, IIf(BBBreakout==1, colorRed, colorWhite));
//set default sorting to Date/time in descending order in results window
SetSortColumns(-2);

Beautiful coding I hope to get as good as you one day. I was wondering if you could make me a code that for strangely that plots intraday high and low throughout the trading day.

def today = GetDay() == GetLastDay();
plot dailyHigh = if !today then Double.NaN else high(period = "day" );
plot dailyLow = if !today then Double.NaN else low(period = "day" );

Also one for extended hours as well

That one is already available here.

@DevilDriver...Thanks but since you didn't post a chart as an example I'm not sure it's what I was looking for... I already have the squeeze code for TOS... I wanted the script to highlight the squeeze on the chart like I showed on the sample chart I posted the link for... [s21.postimg.org]



Edited 3 time(s). Last edit at 02/22/2017 05:23PM by Tampman.

You mean like the big blue clouds are doing in the script I posted?

Didn't have time to post a chart, but I'm fairly certain it's what you're looking for.

If not, let me know.



Edited 1 time(s). Last edit at 02/22/2017 05:26PM by devildriver6.

LOL... well haven't had a chance to paste the script to see what exactly to it looks like.... but was looking for the highlight of the squeeze area as shown in the chart I posted.. if your script does that then I am very grateful for your help... will check when I get home...and load the code.



Edited 2 time(s). Last edit at 02/22/2017 05:27PM by Tampman.

Tampman - yeah, it paints a cloud from beginning to end of the squeeze from the upper to lower Keltner channel.... I'd post a chart now, but I'm mobile at the moment.

OK....cool... will check and let you know but sounds perfect!

Tampman -

Below is the code for one of the first thinkscripts I cobbled together for a bollinger squeeze...

def price = close;
def displace = 0;
def length = 20;
def length2 = 14;
def factor = 1.5;

input averageType = {default sMA, eMA};
def averageType2 = AverageType.WILDERS;

def num_Dev_Up = 2.0;
def num_Dev_Dn = -2.0;

#def shift = factor * Average(TrueRange(high,  close,  low),  length);
def shift = factor * MovingAverage(averageType2, TrueRange(high, close, low), length2);


def average;
switch (averageType) {
case sMA:
    average = Average(price, length);
case eMA:
    average = ExpAverage(price, length);
}

def sDev = StDev(data = price[-displace], length = length);

def MidLine = MovingAverage(averageType, data = price[-displace], length = length);

plot bbUpperBand = MidLine + num_Dev_Up * sDev;
     bbUpperBand.setDefaultColor(GetColor(3));
     bbUpperBand.hideTitle();

plot bbLowerBand = MidLine + num_Dev_Dn * sDev;
     bbLowerBand.setDefaultColor(GetColor(3));
     bbLowerBand.hideTitle();

def Avg = MovingAverage(averageType, data = price[-displace], length = length);

plot kcUpperBand = Avg + shift[-displace];
     kcUpperBand.setDefaultColor(GetColor(7));
     kcUpperBand.hideTitle();
     
plot kcLowerBand = Avg - shift[-displace];
     kcLowerBand.setDefaultColor(GetColor(7));
     kcLowerBand.hideTitle();

addCloud(bbUpperBand, kcUpperBand, color.DARK_GRAY, color.UPTICK);
addCloud(bbLowerBand, kcLowerBand, color.UPTICK, color.DARK_GRAY);

Hope this helps

@netarchitect... Cool Thanks!

@DevilDriver... Thanks Looks great!

Can someone please give me the reversal scanner for ThinkOrSwim! i love the concept and i dont want to spend that much money for a scanner so could someone please be so generous and give me it
Thanks!

1. delete vmoptions.bak
2. -Dsun.java2d.d3d=false
add this line to the end of vmoptions file (not same as bak file)
and overwrite original file

3d acceleration and direct draw .... bye bye



Edited 2 time(s). Last edit at 02/28/2017 03:22PM by elovemer.

@Elovemer -

This is what I currently have in vmoptions:

-Xmx8192m
-Xms4096m
-Djava.util.Arrays.useLegacyMergeSort=true
-classpath/p launcher-first.jar
-Dawt.useSystemAAFontSettings=lcd_hrgb
-Dsun.net.http.allowRestrictedHeaders=true
-XX:MaxPermSize=256m

Any suggestions to further optimize these settings?

Thanks in advance

here is an example .
=========================
-Xms32m
-Xmx768m
-Dsun.java2d.d3d=false

-XX:MaxPermSize=256m
===========================

disabling 3d acceleration and direct draw is described as a performance upgrade for 32 bit machines with lower ram ..... however there is no reason why these would not put a lag on high end machines with high ram.

java ensures that the platform can't be left open no matter how much ram a machine has. it will eventually run out of memory.
---------------------------------------

add the line as stated. if it doesn't work for you, then delete the bak file again and go back to your old saved vmoptions file and restart again.

you also might consider having a platform open for order entry with no charts or saved study sets. and have another platform open for charting.
------------------------------------

by the way... on order entry page if you want a chart......
but you don't want your chart to move around every time you want to modify an order....use the quick chart gadget on the left side for your chart. when the order entry dialog pops up and down, it won't resize your chart. Funny how TOS gives no priority to making order entry easy.

@Elovemer -

Thanks for the swift late night reply. I really appreciate it...

I'll give it a go and report back if there's anything noteworthy to report, that is

This is what mine has.

It loads fast and switches from symbol to symbol really fast now.

-Xmx768m
-Xms32m
-Djava.util.Arrays.useLegacyMergeSort=true
-classpath/p launcher-first.jar
-Dawt.useSystemAAFontSettings=lcd_hrgb
-Dsun.net.http.allowRestrictedHeaders=true
-Dsun.java2d.d3d=false
-XX:MaxPermSize=256m

I'm running 4GB memory so I'd like TOS to have as small a footprint as possible. Even with it set this way TOS runs at 750MB. By comparison Alchemcharts runs at 135MB.

Hi Robert,

Please kindly help me to correct below coding. I don't think TOS has standard ZIG function. thanks in advance.

Def A= ZIG(close,6);
Def BSignal = A>A[1] and A[1]<A[2];
Plot Buy = if BSignal = 1, else 0;
Def B= ZIG(close,10);
Def SSignal = B<B[1] and B[1]>B[2];
Plot Sell = if SSginal = 1, else 0;
Def C=PEAKBARS(2,15,1)<10;
Def D=IF(C=1,2,0);
Def SS= IF(D=2,2,0);
Def MS=IF(SS>SS[1],2,0);
Plot MSell= if MS=2, else 0;

Where would I go to adjust this??

@devildriver6 -

The thinkorswim.vmoptions file path is C:\Users\USER\AppData\Local\thinkorswim...

Rename the thinkorswim.vmoptions file extension to thinkorswim.vmoptions.old before saving the new configuration

Hope this helps...

by the way ... if you want a fixed-range price chart.... the only way i have found to do it is to use " fit studies " .

write a study for the range of price you want... then click "fit studies" .
that way if you show only the current day, you will always have the same range of prices shown on the chart.
otherwise, one bar may take up the same space on your chart as 78 bars for a 5 minute one day chart

this keeps your scaling constant as long as price lies in the range you have programmed and therefore the price bars are not constantly being distorted in size according to how much price history is being shown.

when nothing is happening, price looks big when it is really not (range-wise that is). when things are moving, price starts to looks very small when it is actually much bigger than normal. so when there is big news... you get a tiny 5min bar which is actually 10 points in range.
this distortion is the reverse of what is needed... constancy .

a huge problem with TOS is scaling. there are free programs out there that have much better scaling than TOS does. good scaling avoids the squash effect that happens when you zoom in.

simple things ... are the best indicators.

Good point...With all the blinking lights and gadgetry, it can be difficult to see the forest for the trees...Information overload...

For me...Price, Volume, a little VSA and a couple of homebaked "indicators" work pretty well, but I've been peeling the onion for years now to get to where I am as a trader/investor...

It would be much better if the "fit studies" option only performed that action on the visible candles within the chart window instead of the full length based on the time you selected. For example, if I pull up a daily chart, and select 1 year of data,it will look different than when I select 3 months of data because it applies the "fit studies" to the entire time frame instead of the visible area of the chart window. It kind of annoying.

Windows XP no long fully supports thinkorswim, support will be completely removed in a future release.
For now, some features such as myTrade and chat profiles and video playback will be unavailable.
Please consider upgrading to the minimum supported operating system to ensure uninterrupted access to thinkorswim.

--------------------------

Translation: TOS cares nothing about actual trading. Creating a Facebook of trading is more profitable.


Note: Bull**** like direct 3d acceleration and direct draw are perfect examples of things that do nothing but slow down a platform which cannot even support the weight of its own java base. TOS doesn't care as long as the Facebook thing can grow.
