To make our community more profitable we decided to start a series in which we will review open-source TradingView strategies. The aim of the review is to select a strategy (or a number of strategies) from TradingView and run a reality check on it, optimise them and convert into alerts, so you can set it up as a free trading bot on Wunderbit Trading platform.
This week we found a free stochastic indicator strategy for a 30 min time frame working for long and short entries for BTC perpetual contracts on ByBit Exchnage. The original idea was taken from: 03.freeman . Follow this guide to set up a free ByBit trading bot.
