# New in v9

## Core changes

* **GDAX support:** Gunbot now supports trading at GDAX.
* **Reversal trading:** Enables trading in downtrends by accumulating quote currency without investing extra base. **Do read up on the wiki before you enable this.**
* **New indicators:** You can now use the Stochastic oscillator and per pair MFI as additional confirmation in all strategies.
* **TrailMe:** Most strategies can now use TSSL-style trailing. Additionally, you can use trailing for reversal trading and double up.
* **Custom strategies (beta):** Introducing custom strategies. In this first release of custom strategies it is possible to define your own strategy based on SMA-cross, MACD or MACDH - optionally combined with MFI, RSI or Stochastic.
* **Trading fees:** You can now define the fees Gunbot needs to account for in `TRADING_FEES`. `GAIN` is now a percentage above the expected fees paid.
* **Pair suggestions:** Based on trading volume and volatility, Gunbot suggests possible good pairs to trade on.
* **Automatic retry for TV orders:** Implementing `RETRY_TV_ORDER` to automatically retry orders when processing multiple alerts.
* **TradingView:** Introducing margin trading at Poloniex. All buy orders are now placed as market orders.
* **Dust handling:** `MIN_VOLUME_TO_SELL` is expressed in base currency again.

## GUI changes

* **New design:** new dark color theme, various design refinements.
* **Native charts:** charts based on the same data Gunbot processes, including trades visualization.
