Overview

Set up recurring buys in Gemini. Given some keys (Create API Keys), allows you to configure a recurring buy using the reduced API maker and taker fees in Gemini.

Core features

• Checks current USD balance
• Cancels any existing/trailing orders
• Submits an order for BTC and ETH at X% of current available balance. Sets limit order at 99% of current price. Given the spread and fees, this is likely to fill and is still cheaper than using a market order.

Setup

I'm using AWS Lambda: https://aws.amazon.com/lambda/. The first 1M request/month are free. Given I plan on having this run once a day and/or week, that's more than enough for our purposes. Also having automatic logging allows use to store the order history, tick amounts, etc for free as well.

Using gemini-layer.zip for the core logic with the .py files including the specifics of the purchases. Basic instructions (TBD)

• Upload the layer to AWS Lambda Layers
• Define a function using the rest of the logic
• Run manually or using CloudWatch to schedule a job to run at X interval
