Heiken Ashi Scan

[darkelvis]

Is it possible to create a scanner for ThinkorSwim that will find green Heikin Ashi candles within the last 2 bars or would that be impossible? Thanks in advance.

Here is the scan code for this indicator... I recommend saving two separate scans, one for Longs and one for Shorts... I have tested against my main Watchlist using various timeframes with successful results... Enjoy...

How can I use this script to create scan in TOS?

How can I use this script to create scan in TOS?

Save the script as a Study, reference the Study from within the Stock Hacker Scanner, select the plot desired, set your timeframe, and scan for results... Earlier in this topic I'm fairly certain I posted a link to another topic where I also explained this... This is a standard method of using scripts in scans... By using this method you don't need to constantly edit a script to comment and uncomment multiple plots to get different results...

UPDATE: I have updated the Heikin_Ashi_Trend_Dots_Scan code in Post #8 to insure proper scan results... The previous code was not returning enough results...

Apologies as IM new to inputting the thinkscript into TOS. I was able to input the actual Study script and that works great. But when I cut n paste each of your LONG and SHORT and UNCONFIRMED line text for the Scan I'm confused about where to place the line for LONG and then in a separate but similar scan where to insert the line for SHORT ...and ...which existing line should be deleted from the script you have above. Thanks in advance

@JOMO59 The simplest way to use the Scan Study is to goto the Stock Hacker Scanner, delete all existing filters, click Add Filter, select Study, click on the pencil icon to edit, Delete the existing condition, click on Add Condition, in the Select a condition dropdown select Study, locate your Study name (Heikin_Ashi_Trend_Dots_Scan), select the plot you want to use (long, short, unconfirmed), select is true, click on Save, at the top of the Scanner Custom Filter panel select your desired Aggregation Period, click Ok at the bottom of the panel, make sure you have chosen the proper Scan in selection for your needs, and you are now ready to click Scan or to add any additional filters you may desire... You can then save this scan for future use and optionally set the scan to send Alerts... Repeat the process for any of the other plots you desire to run... You can't break anything by experimenting... Good luck...

The only Plot I get in the drop-down is "haDot" in the scan tab referencing the study. What am I missing. The study was cut and pasted....?

You have the wrong code... Check Post #8 for the Scan code... The only plots in the code are long, short, and unconfirmed... I understand the possibility for confusion... I have been trying to get caught up so I can split this single topic into individual topics for each script...

I was just referencing post #37 and attempting to do it that way..... Went Back to #8 and got it loaded correctly. Thanks

Rad, would it be possible to remove the dots from sub but keep the paint bar?

 

[rad14733]

Rad, would it be possible to remove the dots from sub but keep the paint bar?

@ssmike123 The easiest way to do that would be to use the Heikin_Ashi_Trend_Dashboard from Post #22... I have modified the code to allow hiding the Dashboard if desired... All features, Alerts, colorbars, and the Dashboard, can be enabled/disabled...

I noted that after a long red period it transitions yellow then green, helps isolate significant trend changes
# Added to detect significant trend change
def UpTrend = if haSignal[5] == -1 and haSignal[4] == -1 and haSignal[3] == -1 and haSignal[2] == -1 and ( haSignal[1] != -1 and haSignal[1] != 1) and haSignal[0] == 1 then 1 else 0;
AddVerticalLine(UpTrend,"Bull",Color.Green);

Yes it was added to lower indicator. I was thinking about a loop, fold statement that you could input the number of down signals to calculate the reversal of the trend. So seeing let say 10 down signals and then start turning up which usually means a stronger up trend. Not just looking at down signals but lower and lower down signals. down and lower closes.

Your concept might be best suited for a Scan, Custom Watchlist Column, and/or Chart label...

Hello!
Trying to see if it is possible to create a scanner with the following parameters:

Chart Type Heikin Ashi, daily
MACD parameters: 20,26,9
Chart colors: Green up, red down

Two Types of scans:
BUY
SELL

BUY parameters:
First green bar after a red bar AND MACD line crossing over the signal line (both conditions have to match)
Return results for any tickets that match the above criteria within the last 3 bars

SELL parameters
First red bar after a green bar AND MACD line crossing BELOW the signal line (both conditions have to match)
Return results for any tickets that match the above criteria within the last 3 bars

I looked at the following thread but was not able to create what I'm looking for.

The Heiken-ashi scan is in post#8
and the ToS indicator is MACD

Just looking for an inside bar scanner for heiken ashi candles. There's a plethora of inside bar scanners and the TOS built in scanners would do even I just need to know how to convert that to find them for HA candles instead. Thanks for any help in advance.

That pattern is not appropriate for use with HA candles

have you able to convert this to scanner?

Changing:

def UpTrend

To:

plot UpTrend

makes it scannable

Is it possible to make my scan run scans for Heiken Ashi candles? thanks
