Nest.JS + CCXT Trading Bot

This is a trading bot for a cryptocurrency exchange with an ability to use custom strategies. There are two strategies on the board:

1. FillCells - bot purchase bitcoin with predefined steps (every $50 of rates for example). If there is an already opened order with current rate step found, the purchase is not made.

2. AwaitProfit - bot is waiting for the exchange to rise and try to sell buyed bitcoin. If anual profit percent more that 200% then bot try to sell bitcoin. After 24 hours needed anual profit decreases to 30%.

These simple strategies will guarantee you at least 30% anual profits, just be patient)
