Great, I’m glad you solved it 
Hi.
The syntax for newOrder has changed.
I checked in the exchange API documentation.
restClient.newOrder({
“symbol”: “btcusd”,
“amount”: “5”,
“price”: “3633.00”,
“side”: “buy”,
})
.then(response => console.log(response))
.catch(console.error);

At first I could not install the Gemini API code because Powershell gave me an error which stated that my system is not allowing me to run scripts. To fix this problem I had to go to
( https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-7)
which has all the execution policy codes. It have instructions to run POWERSHELL as an admin and then run “ExecutionPolicy Bypass” which then allowed me to install the gemini api.

I am having problems making the sandbox order, lease assist.
Error Code:

I fixed it by making sure my key and secret are correctly copied and the key part contains “account-”

Greatings to all. I had some problems running PowerSell at the begining. For some reason i found it was blocked from my antivirus(avast) for some reason and i had to restart my computer so it could finally work. Secondly i had the same problem as @CryptoKomuna. For some reason windows 10 has all execution policies set as undefined on my system.
On the foto you can see the first time error for yarn add gemini-api.(first big red paragraf)
Then i typed in : Get-ExecutionPolicy - list with this you can see all the execution policy.
In my case everything is undefined so i choosed the current user . The green underlined is the code to set it off. The system asks you to verify yes, yes to all, no, no to all, suspend, help. I have choosen Y and it worked when i set yarn again. Here is a useful link for this problem like in previous comment @noobon3 mentiond https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-7

Still not working gemini in germany 
I hope there will be soon a cover of the course on another europian exchange like gemini. Any one know about cryptoAPIs or CoinAPI?or another exchance exept bitmex?
After trying things out i found that if you go directly to https://exchange.sandbox.gemini.com/ it also lets germans subscribe even without vpn just use the exact adress of Ivans videos.

I found it a little bit disappointing that I could follow your instructions because I am working with a Mac. Any solutions?

We would need to see your code. But the error code says that you didn’t include a catch block. See lesson 15 " Gemini API Walkthrough"
Building MA Strategy
Javascript bot programming using Gemini API, NodeJS and CryptoCompare
Great lessons that made many things clearer to me! Thank you!
However I found a small coding error:
Ivan changed the console.log commands correctly, but he missed to change the API call for selling the position from marketBuyBitcoin to marketSellBitcoin:
exchange.marketSellBitcoin()
should be correct!

so im trying to create the bot but when i go on terminal and look for the the index.js it wont find it and from there i cant keep going! i tried and tried and nothing is happening
Well, gemini not available in Venezuela, on to another course I suppose, Binance would have worked…
—EDIT----
I have resolved this issue by setting to:
Set-ExecutionPolicy Bypass -Scope UserPolicy
----END EDIT----
ARGHGHG!!! OK I’ve calmed down now. I am having the same issues as others as regards to this message " yarn : File C:\Users\user\AppData\Roaming\npm\yarn.ps1 cannot be loaded. The file C:\Users\user\AppData\Roaming\npm\yarn.ps1 is not digitally signed. You cannot run this script on the current system."
I have tried changing various parameters but there was an override stopping me. I have now reset everything to Undefined… Please advise…
