Thanks Carloz, always appreciated

Hi Carloz, apologies me again

I’ve fixed as per yours above but still getting the error message:

Code as follows:

const GeminiAPI = require ("gemini-api").default;
const secret = "SAXTr4t13WYX5VV2a8rTqaZR8Pb";
const key = "F4C5TcIpdZi3lM7Y1Ilm";
const restClient = new GeminiAPI ({key, secret, sandbox:true});

restClient.newOrder({amount:10, price:100, side:"buy", symbol: "btcusd"});
.then(response => console.log(response));

@Keith2

restClient.newOrder({amount:10, price:100, side:"buy", symbol: "btcusd"});
.then(response => console.log(response));

at the end of the first code line, remove the ;.

Remember that newOrder is an async function so the basic structure is:

restClient.newOrder({
amount:10, 
price:100, 
side:"buy", 
symbol: "btcusd"
}).then(
response => console.log(response)
)

Hi Carloz hope all is well,

Many thanks for your reply, completely makes sense now.

I am however still getting an error message as follows:

PS C:\WINDOWS\system32> Set-Location -Path "C:\Users\dell\Desktop\TradingBot"

Code as follows:

const key = "F4C5TcIpdZi3lM7Y1Ilm";
const restClient = new GeminiAPI ({key, secret, sandbox:true});

restClient.newOrder({

    price:100, 
    side:"buy", 
    symbol: "btcusd"
    }).then(
    response => console.log(response)
    );

Appreciate all your help of late @thecil

@Keith2

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

try to add .catch(console.error) at the end of your .then().

So that will trigger an error message from the server in case you have some error in the parameters.

restClient.newOrder({
amount:10, 
price:100, 
side:"buy", 
symbol: "btcusd"
}).then(
response => console.log(response)
).catch(console.error)

[Keith2]

Thanks Carloz, will do

[Keith2]

Hi @thecil I think we’re getting somewhere, i’ve included the .catch(console.error) and received the following:

PS C:\Users\dell\Desktop\TradingBot> node index.js
{
  result: 'error',
  reason: 'InvalidSignature',
  message: 'InvalidSignature'
}

Could you let me know what the signature refers to?

Thanks again

[thecil]

@Keith2

const secret = "SAXTr4t13WYX5VV2a8rTqaZR8Pb";
const key = "F4C5TcIpdZi3lM7Y1Ilm";

Your key should start with account- then the numbers, verify your Gemini API keys.

I am new to JS and was able to create an image on my computer. Were we supposed to upload an image on Ivan/Tech? Not sure where to put these assignments if they are to be completed on the forum.

Hey @Lorraine, hope you are ok.

I have seen you already find your way to post this question on the proper topic.

Hey @Eduardo_Carrillo, hope you are ok.

You might want to check this guide: https://tecadmin.net/install-yarn-macos/

Also maybe you just need to run your setup through admin role (sudo).

Thanks i could install brew but when i try to install through brew or nps doesnt install.
I even tried with this link : curl -o- -L https://yarnpkg.com/install.sh | bash ‘’ but this happened it needs a profile is not found. can you help me?:

[Eduardo_Carrillo]

just solved it, i had to update my OS. I updated from Sierra to Mojave.

[lacour1]

What do you do if you use Linux?

[thecil]

You can use npm or yarn both are package managers and you can have both installed, i do use both of them (some packages use yarn, some npm).

FAQ - How to post code in the forum

Thanks to @thecil for this guide How to post readable code in the forum You can use the “Preformatted Text” button to encapsulate any kind of code you want to show in your post. The demonstration, below, shows you how, and what the formatted code will look like: function formatText() { let words = "I'm a preformatted text button.
