Im having an error on execution of newOrder function from gemini-api library
API key and secret key required to use authenticated methods
What is that ?
You need a api key for the module to work properly.
API documentation:
https://docs.gemini.com/rest-api/#introduction
Remember to use the sandbox api key (check documentation)

I resolved it
so if we want to use different variable names for Api Key and Secret and not like in gemini-api library then it needs to be declared this way
const APIkey = ck.APIKEY;
const APIsecret = ck.SECRET;
const restClient = new GeminiAPI({key: APIkey, secret: APIsecret, sandbox: true});
or we can just use the same variable name as GeminiAPI library
const key = ck.APIKEY;
const secret = ck.SECRET;
const restClient = new GeminiAPI({key, secret, sandbox: true});
GeminiAPI library
class GeminiAPI {
constructor({ key, secret, sandbox = false } = { sandbox: false })

I’m a bit stuck. My code is as follows:
global.fetch = require("node-fetch");
const GeminiAPI = require("gemini-api").default;
const secret = "2guKgR4uahmHjarfPG8bK6NFEUVN";
const key = "account-BOeBYj3ltMJEOOCNzMgh";
const ccAPIKey = "6e1e4e91e5ade3926c6c3a37ca27bbe3309d56b239b85cc908b95ccc8aabc7f7";
const restClient = new GeminiAPI({key,secret, sandbox:true});
const CryptoCompareAPI = require("cryptocompare");
CryptoCompareAPI.setApiKey(ccAPIKey);
/*restClient.newOrder({amount:10,price:100,side:"buy",symbol:"btcusd"})
.then(response => restClient.cancelOrder({order_id:response.order_id}) )
.then(response => console.log(response))
.catch(error => console.log(error)) */
CryptoCompareAPI.histoHour('BTC', 'USD')
.then(data => {console.log(data)})
.catch(console.error)
When I run this I am getting the following error:
C:\Users\schma\OneDrive\Documents\Trading>node index.js
C:\Users\schma\OneDrive\Documents\Trading\index.js:1
global.fetch = require("node-fetch");

Instead change the require of C:\Users\schma\OneDrive\Documents\Trading\node_modules\node-fetch\src\index.js in C:\Users\schma\OneDrive\Documents\Trading\index.js to a dynamic import() which is available in all CommonJS modules.

I’m not sure why I’m getting the error since I’ve been following along with the videos.
I was able to figure this out. I needed to uninstall node-fetch and install an earlier version.

I had a few troubles getting Gemini API but managed to figure it out.
- I opened PowerShell as an administrator.
- Directed to folder. cd and paste path
- Installed yarn, npm install yarn --global
- yarn add gemini-api (fails, script disabled)
- https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-7 to bypass policy enter Set-ExecutionPolicy -ExecutionPolicy RemoteSigned and hit yes.
- Use the up arrow to run the 4th step (yarn add gemini-api) and enter to install.
This is what I’ve done just in case anyone has trouble. If there are any mistakes please let me know, thank you!
You might need to reinstall yarn, your version is out of date, and probably one of the dependencies needs the latest version to work properly.

I’m very new to all this but i found a walk through on setting up and navigating through PowerShell.

Got It! scrolled through various messages in the forum that were helpful. First made sure the console was up to date and updated dependencies. When making an API Key don’t use the Master key, use primary. Had some missing brackets and added them to the code. I also added
.catch(console.error);
Please need help! I’ve been stuck looking at this code for hours.
index.js
global.fetch = require("node-fetch");
const indicators = require("./indicators.js");
const exchange = require("./exchange.js");
var hasPosition = false;
var strategy = function(){
// If bTC < MA ==> buy (if we have a position)
// If BTC > MA ==> sell (If we have a postion)
console.log(" " );
console.log("=======================");
console.log("Executing strategy");
indicators.hourlyMovingAverage("BTC", "USD", 100, function(ma){
exchange.BitcoinPrice()
.then(res => {
var price = res.last;
console.log("MA: ",ma);
console.log("Price: ", price);
if(price < ma && !hasPosition){
console.log("Buy!");
exchange.marketBuyBitcoin()
.then(res=>{
console.log("Buy successfull");
hasPosition = true;
setTimeout(strategy,1000);
})
.catch(error => console.error)
}
else if(price > ma && hasPosition){
console.log("Sell!");
exchange.marketBuyBitcoin()
.then(res =>{
console.log("Sell successfull");
hasPosition = false;
setTimeout(strategy,1000);
})
.catch(error=> console.error)
}
else{
console.log("Hold!");
setTimeout(strategy,1000);
}
})
});
}
strategy();
exchange.js
const GeminiAPI = require("gemini-api").default;
const secret = "**********";
const key = "account-**********";
const restClient = new GeminiAPI({key, secret, sandbox:true});
module.exports = {
marketBuyBitcoin:function(){
return restClient.newOrder ({amount:1,
price:30000,
side:"buy",
symbol: "btcusd",
options:[ "immediate-or-cancel"]})
},
marketSellBitcoin:function(){
return restClient.newOrder ({amount:1,
price:10,
side:"sell",
symbol: "btcusd",
options:[ "immediate-or-cancel"]})
},
BitcoinPrice:function(){
return restClient.getTicker("btcusd");
}
}
indicators.js
onst CCAPIKey = "************"
const CryptoCompareAPI = require("cryptocompare");
CryptoCompareAPI.setApiKey(CCAPIKey);
module.exports = {
hourlyMovingAverage:function(cryptoAsset, fiatCurrency, hours, callback){
if(hours>169){
console.error("Only up tp 169 hours allowed!")
return
}
CryptoCompareAPI.histoHour(cryptoAsset, fiatCurrency)
.then(data => {
data = data.reverse()
var sum = 0;
for(var i = 0;i<hours;i++){
sum+=data[i].close;
}
var movingAverage = Math.floor (sum/hours);
callback(movingAverage);
})
.catch(console.error)
}
}
Does the console shows any error when you run the code?

Could you please share your code in the following way?
Carlos Z
Problem solved I think it was the spacing at the very top function.
var strategy = function(){
IT WORKS!

node-fetch changed to ES modules by default:
SOLUTION:
- Uninstall the current version of node-fetch with
npm uninstall node-fetch - Install the second version:
npm install node-fetch@2
It has worked for me!

Heyy there. I am having problems with the gemini web page, I don’t know what to do. Can someone, help me pls?
what is your issue?
https://exchange.sandbox.gemini.com/balances check this website you should be able to have an account;
make sure you validate your account by clicking on the email from gemini or an sms sent to your phone. otherwise the API settings wont work.
then go to settings and set your API; avoid the master key to use ; create a primary API and save it.
example:
const GeminiAPI = require("gemini-api").default;
const secret = "< secret key";
const key = "account-secret account key";
const restClient = new GeminiAPI({key, secret, sandbox:true});

all right i finish the course
and the forum was great to fix some of the updates/ on the node-fetch upgrade … i got stuck but the forum saved me time 
the only change I made on the code is to set the MA value to added into my sell or buy bitcon at the MA price; so i will buy or sell something instead of a fix number; i increased timer to 10 sec… so i can catch with my slow 
the results
in indicator.js file
module.exports = {
marketBuyBitcoin:function(ticker){
return restClient.newOrder({
amount:1,
price:ticker,
side:"buy",
symbol:"btcusd",
options:["immediate-or-cancel"]})
in index.js
exchange.bitcoinPrice(ma)
.then(res => {
var price = res.last;
console.log("MA :", ma);
console.log("Price :", price)
if(price < ma && !hasPosition){
console.log("BUY!")
exchange.marketBuyBitcoin()
.then(res => {
console.log("bought successfull");
hasPosition = true;
setTimeout(strategy,10000);
})
.catch(error => console.error)```
Thanks Aldrin, let me look into that. If I cannot move on, Could I request your help?
