Invalid Price

[tacp17]

After the bot makes a buy I am getting this:

executeAlgoForWhenLastOrderWasBuy() - BTC/USD ^^^ Yay!!! Last BUY Order Id [776165985] filled at [2402.37]

java.io.IOException: Server returned HTTP response code: 400 for URL: https://api.gemini.com/v1/order/new

I tried editing the price decimal places in the Gemini exchange adapter to only 2 decimal places but i get a build failure when i try to create a new bot. Thanks for any help and sorry if this isn't the right place for this.

Thank you!

Bit late to the party, but I've got a fix going in.

I've only been trading on the ethbtc market due to the early US/UK trading restrictions. The market price currency (BTC) price value is limited to 5 decimal places and I was rounding in the trading strategy.

As you've discovered, when USD is the price currency, it needs rounding to 2 decimal places.
