QUESTION
The VuManChu Cipher B + Divergences indicator script shows the buySignalDiv condition on the chart as a big green dot, but the alert is triggered only after 2 bars confirmation.
here is example of alert delay
I think the problem is in this piece of code where offset = -2
.
The solution would seem to be simple, put 0 and the alert function delays for two candles will disappear. It is, after that alert comes as soon as the green dot appears on the chart, but here is the problem, now the green dot appears two candles later than it is needed for a profitable entry into the trade, as I noticed. The same happens with sellSignalDiv
and like wtGoldBuy
and others too.
Question: how to make alert come in time, after the candle closed and not 2 after that, and at the same time, the offset = - 2
, so it can show profitable signals? Mixed with 3commas bot and low TP and SL too, with some leverage, script could make at least 80% profitable deals and be pretty useful.
ANSWER
Answered 2022-Apr-07 at 20:09You cannot.
Using offset
here is cheating in my opinion. You are displaying information from future as it was hapenning now.
I could easily write a script that looks for 10% price jumps and plot a buy signal some bars ago with offset
as if it was predicting that price jump.
Your entries will always be 2 bars late. You should either live with it or look for other scripts.
QUESTION
I have been working on an ASP.NET MVC 5 web application using Entity Framework 6 as an assignment for my Business Programming II class. Despite the fact that I know very little about programming, I have been making progress, but I have run into trouble. I am supposed to write CRUD operations for an online storefront based on the Northwind Traders database. I already have working code for reading from the database as well as adding and updating items in the database. Where I'm struggling is deleting items. The following requirement is listed in the assignment description:
Delete a product by making it discontinued so that the information is displayed in the database. Do NOT actually delete a product from the database.
I've tried a couple things to try and make this work, but all have failed for various reasons.
Here's the code to my current Delete
View (ignore any strange HTML formatting decisions, right now I'm focused on getting this functional):
ANSWER
Answered 2022-Apr-04 at 01:37Your Delete logic seems fine. What I would look at in more detail is your Edit.
Overall I am not a fan of ever passing Entities between the server and the view, especially accepting an entity from the view. This is generally a bad practice because you are trusting the data coming from the view, which can easily be tampered with. The same when passing data from a view to server, this can lead to accidentally exposing more information about your domain (and performance issues) just by having some "sloppy" JavaScript or such converting the model into a JSON model to inspect client-side. The recent case of the journalist being accused of "hacking" because they found extra information via the browser debugger in a Missouri government website outlines the kind of nonsense that can come up when server-side code has the potential to send far too much detail to a browser.
In any case, in your Edit method when you accept the bound Product after deactivating the Discontinued flag, what values are in that Entity model? For instance if you use Delete to set Discontinued to "True", then go to the Edit view for that product and un-check that input control and submit the form, in your "product" coming in the Edit page, what is the state of the product.Discontinued?
If the value is still "True" then there is a potential problem with your page binding where the EditorFor is not linking to that flag properly or the value is not deserializing into the Product entity. (a private
or missing setter?)
If it is coming back with what should be the correct value, then I would look at changing how you update entities. Code like this:

I am new to Firebase Cloud Functions and have been struggling with adding private npm packages to make my functions work. I understand Firebase will treat them all as public unless specified and will install with npm / yarn what I have in package.json.
The only way for me to tell Firebase that it's a private repository on Github is to add a
.npmrc (containing) - The key I am using is a Personal Access Token from Github-Developers that has all the need it permissions

Answered 2021-Nov-01 at 08:22After the rest of the day searching for the answer it was the most simple but not the wisest solution that worked:

...ANSWER

objects - i.e. you can just do q.ask_price
to get the price from the received Quote
s.
In your quote_callback
function you get every Quote
object as an argument. So, if you always only want to access the last received Quote
object which has symbol
= "HB"
, you could define a global dictionary named e.g. quotes
which will contain one key == symbol and value == last Quote
with that symbol per symbol type.
Now, in get_quote
you can use a simple dictionary lookup for the desired key in the quotes
dictionary. In the end, you need to repeatedly call get_quote
until a quote object with the desired symbol value is received. The whole code could look like this:
QUESTION
I am using a binary crossentropy model with non binary Y values & a sigmoid activation layer.
I have created my first custom loss function but when I execute it I get the error "ValueError: No gradients provided for any variable: [....]"
This is my loss function. It is used for cryptocurrency prediction. The y_true are the price change values and the y_pred values are rounded to 0/1 (sigmoid). It penalizes false positives with price_change * 3
and false negatives with price_change
. I know my loss function is not like the regular loss functions but I wouldn't know how to achieve this goal with those functions.
ANSWER
Answered 2022-Jan-05 at 08:08I found the correct differentiable code for the loss function i wanted to use.
QUESTION
Does anyone know how I can plot each occurrence of a defined variable after a certain date? So, before a certain timeframe input ignore all occurrances. I was able to find this:How to plot only the last x periods But, this appears to only plot a single occurrance of the variable on the input date.
For example and simplicity how can I plot every doji after the user input date:
...ANSWER
Answered 2021-Dec-29 at 22:45Great question Josiah, there is a lot going on here:
- You probably already discovered this, but the
beginMonth
test in the code sample above, as written, will only flag the first day of the first full month that is in your allowed date range. We'll fix that below. - There are some related changes in Pine v5 to how colors are set, and from v4 as to how variables are declared and updated, so I have leveraged those below as well.
- You have two tests going on: timeframe and doji-ness, so I've split them up below for clarity.
This was a great example to work with because it highlights a problem I often have in my own Pine scripting, looking for opportunities or conditions:
Why don't I see any opportunities flagged by my rules? Is there something wrong with my code? Did it even run? Or is it the data I'm looking at, in there just aren't any matching candles, but the code is fine? (Oh, and am I reading the wrong version of the documentation, using the correct version of the function, updating the values on each bar or not...)
Even when we succeed in crafting the correct tests and succeed in combining them properly, it's still very hard to effectively plot dojis. Partly because they're rare, and partly because of what they look like on a chart. That also makes it hard to tell if our code is working, even when it is.
So I try to make sure my code helps me see just what's going wrong and what isn't. And hopefully this example is useful to others on that level as well.
The code below should do what you want. To answer your headline question, it uses a variable called okayToPlot
to limit rendering of your indicator to just days in the past N months.
It also shows how find and effectively highlight doji's, so you don't go insane trying to see a thin black line that was rendered on top of another thin black line.
I used overlay=false
to help you (okay, me) get a better look at what was going on. Once you're satisfied with your working script, just change it back to overlay=true
and you're good to go.
If you copy/paste this into your Pine Editor as a new Indicator and try it out on a daily chart for some slow-moving large cap stock, you should spot a doji if you scan a long enough period.
I used 8 months on BCE on the TSX in late 2021 and it finds 2 days with a doji formation, which it highlights with a yellow background and a bright green + sign.
