'{ period: any; 类型的参数价格：任意； }' 不可分配给类型为 'MAInput' 的参数

Question

I want to use technicalindicators in my Angular app written in TypeScript, but don't know how to import and use it?

What I want to do is calculating SMA(Simple Moving Averages) of an array.

EDIT:

I have installed technicalindicators module using npm i --save technicalindicators command. Then I imported it like this:

import {sma} from 'technicalindicators';

Then I tried to use it like this:

var prices = [1,2,3,4,5,6,7,8,9,10,12,13,15];
var period = 10;

  doSMA(period , prices){
    console.log('sma result is:' , sma({period, prices}));
  }

But I get this error message:

Argument of type '{ period: any; prices: any; }' is not assignable to parameter of type 'MAInput'

Looks like you can use it no problem.. From the source, they have the TS interfaces already.

You just need to npm install --save technicalindicators

And to use it, you would import in your angular project the same as any other, have you tried it ?

for example :

import { StockData } from 'technicalindicators';

EDIT as per your error:

Following the documentation, the sma method requires 3 params.

eg:

sma({period : 10, values : [1,2,3,4,5,6,7,8,9], reversedInput : true});

From what I can see, it looks like you want to use a SMA.calcultate .

SMA.calculate({period : 10, values : [1,2,3,4,5,6,7,8,9]});

The error is quite clear though.
