Hey,

Is it possible to somehow get a list of all indicators that are added to the strategy when inside the observer next() method. I know that we can access datas, broker, trades and orders data via
self._owner attribute. The indicator objects are listed there as well, so we can access them.

However, is there an attribute which holds a list of all indicators that are added to this strategy? So we could actually loop over indicators and would not need to have a prior knowledge of what indicators are added.

@sp I'm looking into same thing right now and would like to see if you guys figured it out.

Can you drop me a line if you had any progress with this.

Thanks!

Hi,

I want to implement forward/paper trading using the backtrader. I have already more-or-less figured out how I will get the latest data. I will write a custom module which will monitor ticker-time pairs that user specifies on tradingView and if any of those has a new candle released then it will retrieve that and append to data set.

I was thinking that in my strategies Next method I will check if the current sample is the last one and if it is then it will just block until there is a new sample in the data feed. Before that it will run as normal so we can start with historic data and then transit into forward testing (good because then all the SMA and other such indicators are already up and running).

However, the difficult part is how to append those new candles into backtrader data feed while the test is running. Is there a way to append data into data feed while the test is running or would that break the test?

Answering my own question.

The order.ref answer that was given in that forum post actually works. My mistake was that I wanted to get the attributes directly and compare them. However the order class has overwritten the == method in which itself it compares ref attributes.

So instead of

if self.tradeid == order.ref:

I had to write

if self.tradeid == order:

Hi,

How would it be possible to get the tradeid value of the order in notify_order method when the status of the order changes. For example, when my order gets completed I would like to check via tradeid which order it was.

I found this forum post, but one of the answers did not work (int object has not attribute "ref" error) and the other answer was as useless as it can get.
