Backtesting Live Ticks Possible?

NewestTrader

Hi,

using ibtest.py --data0 EUR.USD-CASH-IDEALPRO --timeframe Seconds --compression 30 --port 7497 --replay seems to be the best way to

have live tick data
to get properly shaped live data candlesticks for candlestick periods that lie in the past (even without backfilling the data that came up before the script was started).

(see: https://community.backtrader.com/topic/998/best-approach-for-live-trading-with-cheat-on-open/12# )

My question is: during pure backtesting: is it possible to get the data in next() the same way as I get it during live trading?

(so like this mix out of well shaped candlesticks and arbitrarily occuring "live" ticks)

Thanks in advance!

Of course. Create a data feed which has that behavior and you will get it.

thanks for your reply, @backtrader , but I just wonder how I can do that?

With every row in my csv file, len(self) in next() will increase by one from one call to next()to the following call.

In contrast to that, during live trading len(self)only increases, when the next timeframe is reached. But in between, several ticks could have come up that do not lead to an increase in len(self).

Big thanks in advance!

If you have ticks in your data feed and you replay it to a larger timeframe, you will get that behavior too. But you need to have ticks stored, which is not the most usual setup.
