SimpleBot

SimpleBot is a Python bot implementing a scalping trading strategy. It can work with any assets pair on the Waves DEX.

SimpleBot exploits small changes in currency prices: it buys at the mean price minus some step and sells at the mean price plus some step, in order to gain the bid/ask difference. It normally involves establishing and liquidating a position quickly, in this case within 15 seconds.

The SimpleBot with initial parameters trade on Waves-BTC pair (Waves is an amount asset and BTC is a price_asset). The spread mean price is (best_bid + best_ask) / 2. The price step is 0.5% from mean price. The SimpleBot place the buy order at price meanprice * (1 - price_step) and the amount (BTC_balance / bid_price) - order_fee. The sell order is placed at meanprice * (1 + price_step) and the amount equal to Waves_balance - order_fee.
