 Backtrader Python client is located here: [Python Backtrader - Metaquotes MQL5 ](https://github.com/khramkov/Backtrader-MQL5-API)
 
+Thanks to the participation of [freedumb2000] (https://github.com/freedumb2000), the project moved to a new level.

+New features:
+
+- support for multiple datastreams in parallel for any combination of symbols and timeframes independently of the timeframe and symbol of the attached chart
+- support for tick data
+- support for direct download as CSV files
+- automatic retry binding to sockets. When running under Wine in Linux, sockets will be blocked for 60 seconds if closed uncleanly. This can happen if the client is still connected while the EA gets reloaded.
