High Low Lookback for ThinkorSwim

[Pensar]

@Armageddon Please be specific. What symbol? What aggregation? Do you have extended hours on or not? Is "Fit Studies" checked or un-checked? In order to try to help, you must provide the information necessary to attempt to duplicate the problem. It would also be helpful to post a screenshot of the problem in addition to the answers for my questions.

@Armageddon Perhaps try this -

input endDate = 20210104;
def cond = if GetYYYYMMDD() < enddate then double.nan
           else if GetYYYYMMDD() == endDate then low(period = aggregationperiod.day)
           else cond[1];
plot Price = cond;
Price.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

           else cond[1];
plot Price = cond;
Price.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

Super! One question solved!!! On the daily chart, everything is super!! Thanks!!There's only one thing left. I turn on the graph (example) 5 days 5 minutes or 2 days 1 minute and the level becomes "0". "Fit Studies" turned on and the indicator appeared at the level " 0 " and turned off, then the indicator disappeared.

How to attach a photo here is not easy to understand?

@Armageddon Can you see 01/04 on your chart? You need to be able to see the inputted date for the script to work.

Edit: Okay just saw the newer post. Your chart needs to include the inputted date for it to work.

Ahhh! It's a pity if you can't do it. Just a date can be a year ago and a short timeframe for a year is a lot. But thanks for your help anyway!!!

Kory,

Curious on your coding for the stochastic indicator. When the indicator is overbought, I need it to look at the current price and compare it to the price the last time the indicator was overbought. If the current price is lower then I need the indicator to paint red. Same thing for oversold except if price is higher currently than previously, the indicator would paint green. If these conditions are not met when oversold or overbought, the indicator would be cyan. Any help would be appreciated.

@maston21 you can either use a fold (loop) to look back, or what i might do is just carry forward prevPriceOverbought/Oversold variables from the last signal.

psudeocode:

if (overbought)
prevPriceOverbought = close
else
prevPriceOverbought = prevPriceOverbought[1]

and just use it when you wish to compare

@korygill I tried to copy and paste the above code however it is showing a error.

This is what im trying to do........

What @korygill provided was example code. To illustrate ThinkScript logic and syntax.
It is not meant to be used as is.

good stuff

How do I modify the script to exclude the current candle?

How do I modify the script to exclude the current candle?

There is no way to do that in this snippet. Perhaps after you add it to your script. You can subtract the current candle from your resulting calculations.

I was working on a request from a friend for highlighting a bar a given number of bars back, and then tracking the subsequent highest high and lowest low from that bar.

This ties into some other work I can share later where you can see where the most recent bars are relative to a lookback period like you might use in a SMA or Stochastic, etc.

Here is what the study looks like on a Ford (F) 1Y 1D chart.

Some things to notice:

• labels
• chart bubble at (high+low)/2 on the lookback bar
• purple squares at high and low on the lookback bar
• purple squares have Bubbles hidden (on the right vertical axis)
• LOW chart bubble
• LOW line
• HIGH chart bubble
• HIGH line

Keeping track of and calculating which bar numbers are meaningful is fairly straightforward, but did take me a few attempts to get right. Debugging with labels helps a lot to troubleshoot some issues, and plotting values can also be a good diagnostic tool.
