poloLender Pro is:
- an open source application written in JavaScript
- runs on node.js
- can either run locally on your computer or can be hosted on a cloud platform (e.g. Heroku).
poloLender Pro is an automatic bot which lends funds on Poloniex exchange.
The lending rate is calculated using statistical calculation in order to maximize profits.
poloLender Pro does not calculate the lending rate itself, instead the poloLender Pro receives the lending rate from poloLending-Advisor server. poloLending-Advisor is an on-line server hosed at http://safe-hollows.crypto.zone.
In order to calculate optimal lend offer rate, the server continuously monitors the lend-book (active offers) and also calculates the average loan holding time. Based on this data and using statistical calculation poloLending-Advisor server can inform poloLender Pro clients of the rate with best profit returns.
By using historical information and statistical calculation poloLender Pro is able to give better return rates, as comparing with placing offers only looking at a snapshot of the lend book.
As it can be seen in the screen-shot below, poloLender Pro, manages to place offers with good rates
Other existing bots are placing loan offers by only looking at a snapshot of the lend-book (active offers available at one point in time). To find out why snapshot of the lend-book does not give information on best return rate, I have written a bot that places small lend offers at the top of the lend-book every minutes.
As you can see in the screen-shot below, often the lend book rates vary widely. For this reason, figuring out the rate that gives best result is not obvious.
In addition, placing offers "randomly" through the lend-book, expecting a spike is not most efficient.
Running on Heroku is highly recommended to ensure maximum up-time.
