New features / changes in v15
Over 100 new supported exchanges: Gunbot now supports spot trading on all exchanges supported by the ccxt library! This includes support for email alerts through the TradingView add-on.
Trading fees setting moves to exchange section: for easier strategy handling, the TRADING_FEES setting is now configurable per exchange. It's no longer a strategy setting.
Limit orders for TradingView add-on: optionally you can now let the TradingView add-on place limit orders instead of market orders.
Pre-release of AutoConfig: with AutoConfig you can automate all kinds of things you previously could only do by hand. For example you can use it automatically add high volume trading pairs, assign a bag handling strategy for pairs that are not performing well, or automatically update pair overrides. It's called a pre-release because there no GUI for it yet, it's fully functional though.
