  @xiaoy0521 on https://github.com/ftomassetti/backtrader-oandav20 there is some installation guide. In the directory examples, you will find oandav20test.py . This may help you get started. also you need v20 instead of oandav20. pip install v20

  Just saw these other posts. https://community.backtrader.com/topic/719/using-ib_insync-rather-than-ibpy/6 https://community.backtrader.com/topic/623/anyone-use-backtrader-to-do-live-trading-on-bitcoin-exchange/2 If anyone can point me to the correct docs or any other tutorials that discuss adding your own custom data/broker layer that would be extremely helpful. Thank you.

  @darr said in Updating backtrader to connect the IB supported IB API ?: I have been having trouble It's always good to say there is trouble, but not actually what is the trouble. @darr said in Updating backtrader to connect the IB supported IB API ?: Are there any current plans to create a new set of IB Broker files to work with the new client API from IB? https://community.backtrader.com/topic/376/eodevelopment-1-x @darr said in Updating backtrader to connect the IB supported IB API ?: Please me know your thoughts on this one. Feel free. See this for example: https://github.com/ftomassetti/backtrader-oandav20

  I think you are expecting too much from a calendar. The calendar does only provide information about when the market is open, which for allows synchronization of multi-timeframe feeds (because suddenly the system knows that the asset doesn't trade on Saturdays and the resampler doesn't have to wait until Monday) The calendar is not omnipotent and won't filter the data for you. @raptor said in Calendar Problem - GenericCSVData: the system is still buying on holidays and at night. That means you are actually putting data in the system for such occasions.

  @jeff-lee said in How to buy-open an order and sell-open an order at same time? I means lock the order in futures: yes, I just want to have both of the two direction orders(long-open, short-open) at the same time. So presented it is an impossibility. Your problem is probably that you have only daily bars and your goal is to simulate an intraday strategy. The solution is to have intraday data.

  I am also trying to use the CCXT lib from https://github.com/Dave-Vallance/bt-ccxt-store. The feed works very fine with 1 minute time frame. But with other compressions, does not work. I also tried to add to cerebro with: cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes, compression=5) But does not work too. @guwop do you have some progress with it?

  @ab_trader Sorry what do you mean by provider info? Are you referring to where the DDE feed is sourced from? If so, it is a program called "Spark" by Iguana 2.

  There were several patches to resampling, which probably had an impact on rightedge. Use this code as a template to achieve your desired effect. rd = cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes, compression=5) def _new_load(self): ret = self._old_load() if ret: dt = self.datetime.datetime(0) self.datetime[0] = bt.date2num(dt - datetime.timedelta(minutes=5)) return ret rd._old_load, rd._load = rd._load, _new_load.__get__(rd, rd.__class__)

  @nomad5am said in Send trade events to API/webhook for execution: we would like to send the trades from Backtrader to our Bot API/Webhook instead of the broker You have missed how things work. A Broker in backtrader is simply an interface to something. The default broker is meant for backtesting, but this can be replaced by other brokers, which ma interface to API, Webhooks or to whatever you want. This is what the integrated brokers for Oanda (v1API), Interactive Brokers´ andVisualChartdo. An example of an independently developed broker (Oanda` (v2API)) https://github.com/ftomassetti/backtrader-oandav20 For examples of how to change brokers Docs - Interactive Brokers The Cerebro reference Docs - Cerebro

  No. And it has been discussed in the past several times: backtrader is not a bid/ask platform, even if it can be forced to partially use the values due to built-in extension capabilities. But something like next_orderbook has nothing to do with the design per se.
