kandi X-RAY | Blotter Summary

Blotter is a JavaScript library typically used in User Interface, Graphics, WebGL applications. Blotter has no bugs, it has no vulnerabilities and it has medium support. However Blotter has a Non-SPDX License. You can download it from GitHub.

When applying effects to text on the web, designers have traditionally been constrained to those provided by CSS. In the majority of cases this is entirely suitable – text is text right? Yet still, there exist numerous examples of designers combining CSS properties or gifs and images to create effects that evoke something more playful. Precisely here, Blotter exists to provide an alternative.

How can I order the column values that appear in a Filter list in ag-Grid and AdapTable?

Asked 2020-Dec-22 at 17:28

We have a user requirement that the values in a date column in our ag-Grid Trade Blotter are shown in reverse order (i.e. most recent first).

Is there an easy way to do that?

We are using ag-Grid 23 with Adaptable 7.2.5.

Answered 2020-Dec-22 at 17:28

There are 2 ways of doing it:

Easy way - set the 'sortColumnValuesInFilter' property in Filter Options to true in your Adaptable Options (see https://docs.adaptabletools.com/docs/adaptable-options/filter-options) and then it will display items in the filter using whatever sort the column currently has.
More complicated and powerful way - provide a getColumnValues implementation. This is a user function which is run whenever AdapTable needs to show distinct values in a column - so you can decide which columns to apply it and then sort the return list however you want (see https://docs.adaptabletools.com/docs/user-functions/get-column-values-user-function)

VueJS event handlers being rendered before DOM content is completely loaded?

Asked 2020-Jun-04 at 09:36

I am building a Vuejs application, so I am using the @mousemove directive in conjunction with Vue-blotter. Below, under the "Interaction example" section, I found some base code for manipulating the component properties. So with a minuscule bit of refactoring, I added it to my project and changed the scope.material.uniforms.uSpeed.value = (e.x + e.y) / 4500 found in the sample to scope.material.uniforms.uSeed.value = (e.x + e.y) / 2000 also a valid property, as will be shown later. The problem is that if I move the cursor before the page is completely loaded the console will display this error:

Error in v-on handler: "TypeError: undefined is not an object (evaluating 'scope.material.uniforms.uSeed')"

This error stops being outputted even if I move the mouse after the page is completely loaded. I am using Vue-router and this is how my Home view looks like:

QUESTION

How to bootstrap in R

Asked 2020-May-15 at 10:48

I obtained the returns of the RUT index running a backtest in R in Quantstrat. Now I would like to create a bootstrap of the returns but I do not know how to do it. I know that the boot() function needs data, statistic, and number of bootstrap repetitions. In data I think I can add "returns" ( see code below ) But I do not know how to compute "statistic". Can someone help?

Please refer to the code below:

...

ANSWER

Answered 2018-Jul-14 at 19:36

Here is a simple example of boot() [based on Chapter 5, Page 196 in ISLR] to calculate bootstrapped mean of a column in a dataframe. (R version 3.3.0). The boot() function needs data, a function that calculates a statistic of interest and number of bootstraps 'R'. Here, the function has to have two inputs i.e. data and an index to iterate.

No transactions/positions to Chart Quantstrat, "logical" error?

Asked 2020-May-15 at 10:46

I get the error message that the are no transactions/positions to chart despite the use of signals and rules. Can someone explain me what I am doing wrong? Is it maybe in the logical development of rules? I want my rules to do what follows: Enter long AND exit short if CNOwma crosses above 0.6. Enter short AND exit long if CNOwma crosses below 0.6. Please refer to the following code. The error is in the last line.

Thank you.

I solved the issue.

A lot of errors arising with backtesting in Quantstrat are due to misspecification of column names.

This issue is due to a change in IEX trading api which now requires an API key (account) to query it. I hope that it will be corrected and clarified in the documentation in the future and that retrieving data from external APIs would be much more easier.
