GdaxBuyer

I wrote this to monitor trends and look for peaks and bottoms to get in and out of the market at the right time.

Examples

• To run the seller (min peak finder):

LAST_PURCHASE_AMT=5267.02 LAST_PURCHASE_PRICE=295.68 MIN_PROFIT_PEAK=10 node seller.js

LAST_PURCHASE_AMT

The purcahse amount of your last order

LAST_PURCHASE_PRICE

The price of the cryptocurrency at the time of the purchase

MIN_PROFIT_PEAK

The amount the currency should increase by in order to trigger the alarm/sale.

---

• To test a break even point:

LAST_PURCHASE_AMT=5267.02 LAST_PURCHASE_PRICE=295.68 MIN_PROFIT_PEAK=10 TLP=300 node seller.js

TLP

Emulate the seller on a would-be ticker price see profit/loss

---

• To run the buyer (bottom finder):

PRODUCT_ID=BTC-USD MM=1 node buyer.js

MM

The Min Bottom: Whatever value is provided here will sound an alarm when the bottom is reached.

PRODUCT_ID

The GDAX token for the product id. you can omit this paramter and default to $.defaults.productId in your configuration.
