#-POLONIEX LENDING BOT-#

R00TC0IN's
Advanced poloniex lending bot is coded in Python!

The bot features automatic lending on the exchange at Poloniex.

It will automatically lend all crypto currencies found in your lending account.

It uses an advanced lending strategy which will spread offers across the lend book to take advantage of possible spikes in lending rates.

I also have a trading guide full of trading information and how to guides for new and advanced traders.

Features

Automatically lend your coins on Poloniex at the highest possible rates, 24 hours a day.

Configure your own lending strategy!

Be aggressive and hold out for a great rate or be conservative and lend often but at a lower rate, your choice!

The ability to spread your offers out to take advantage of spikes in the lending rate.

Withhold lending a percentage of your coins until the going rate reaches a certain threshold to maximize your profits.

Lock in a high daily rate for a longer period of time period of up to sixty days, all configurable!

Automatically transfer any funds you deposit (configurable on a coin-by-coin basis) to your lending account instantly after deposit.

View a summary of your bot's activities, status, and reports via an easy-to-set-up webpage that you can access from anywhere!

Choose any currency to see your profits in, even show how much you are making in USD!

Select different lending strategies on a coin-by-coin basis.

Run multiple instances of the bot for multiple accounts easily using multiple config files.

Configure a date you would like your coins back, and watch the bot make sure all your coins are available to be traded or withdrawn.

#Enter ALL to transfer all coins, enter ACTIVE to transfer any coins you have in your lending account when the bot starts, these can be mixed.

#Keep Stuck Orders - Sometimes an order gets partially filled. When this happens it may leave the remainder of your coin under the set minloansize.
