Invalid argument 'display' in 'plot' call. Possible values: [display.none, display.all]

I am writing a pine script code to plot some lines conditionally. I see pine script v5, plot() function has display argument, still I am getting an weird error. Any idea what it could be?

You should apply your condition to the series argument of plot(). The display argument is whether to enable or disable the plot by default and I believe it must be a constant.

And you probably want to change the style to something like plot.style_circles so your line won't be connected.

How can I view Pine Script for built-in indicator - like Gann Box?

Asked 2022-Jan-26 at 09:54

I would like to write a Pine Script for something similar to the built-in Gann studies. Is it possible to view the source code for these, so I don't have to "re-invent the wheel"?

Any suggestions?

You cannot see the source code of every built-in indicators. Gann box is one of them. So, you have to do your own research and code it yourself.

QUESTION

How to add an alertcondition for this TradingView indicator

Asked 2021-Jun-08 at 00:58

I have a TradingView indicator in Pine Script, which I use for my trading strategy, but it doesn't have alerts in its code, and as a result, I miss some trading opportunities.

This indicator is a simple moving average SMA of the previous n period's highs or lows.

The indicator tracks both curves (of the highs and the lows). The close of the bar defines which of the two gets plotted.

I want to add a BUY alert when the price crosses the red line and a SELL alert when the price crosses the green line, but I don't have any experience in Pine Script.

I am attaching below the indicator's code and the screenshots. I would appreciate any help in adding these alerts.

QUESTION

How do I query the best solution of a pyGAD GA instance?

Asked 2021-Jan-18 at 06:27

I've trained a population of neural networks using using the genetic algorithm implementation provided by the pyGAD Python Library. The code I've written so far is given below:

ANSWER

Answered 2021-Jan-18 at 06:27

Thanks for using PyGAD.

I see that you built the example correctly. You can easily use the best solution to make predictions using simple 3 steps.

Please note that after each generation, the population attribute is updated by the latest population. That means after PyGAD completes all the generations, the last population is saved in the population attribute.

Step 1

After you load the saved model using the pygad.load() function, and as you did in the fitness function, you can use the population attribute to restore the weights of the networks as follows:

How Do You Thread an External Hanging API Call in Flask?

Asked 2020-Mar-05 at 04:56

Getting the specifics out of the way, I'm writing an open source P2P social network over IPFS and Flask -- I know, it's been done. I'm choosing Flask because pyinstaller can put it in an exe file.

I am attempting to update my IPNS every 10 minutes to publish all status updates I've added to the network during said 10 minutes. The cron function from setup class (from library.py) is where that updater function is stored. At first, I threaded the cron function from init of setup. The server hung. Then I moved the threading process over to app.before_first_request. The server still hangs.
