Backtest strategy using Oanda historical data ? about autotrader HOT 5 CLOSED

This looks like a bug I've introduced in v0.7.0. I'll work on a fix for it now.

In the meantime, a workaround would be to download the data first, then run the backtest by providing the local data filepath.

To download the data:

from autotrader import AutoData

data_config = {
    'data_source': 'oanda',
    'API': 'api-fxpractice.oanda.com',
    'ACCESS_TOKEN': 'xxx-yyy',
    'PORT': 443,
    'ACCOUNT_ID': 'xxx-xxx-xxxxxxxx-xxx'
}

ad = AutoData(data_config)
data = ad.fetch(instrument='EUR_USD', granularity='1h', count=100)

To run a backtest with local data, refer to the docs for add_data.

I'll aim to have a fix out in the next few hours.

@GL-Software This is patched now with v0.7.1, so you can either update by pulling the latest from the repo or by running:

pip install autotrader --upgrade

Note that the configuration keys required for Oanda have changed slightly to clarify what they are to be used for. You can refer to the account configuration docs for the new keys, but feel free to ask here if it is not clear.

For complete reference, this is the runfile I have used to verify the fix:

from autotrader import AutoTrader

at = AutoTrader()
at.configure(verbosity=1, show_plot=True, feed='oanda', mode='periodic')
at.add_strategy('macd')
at.backtest(start = '1/1/2022', end = '1/5/2022')
at.virtual_account_config(initial_balance=1000, leverage = 30)
at.run()

And this is my account config for Oanda (config/keys.yaml):

OANDA:
  LIVE_API: "api-fxtrade.oanda.com"
  LIVE_ACCESS_TOKEN: "xxx-yyy"
  PRACTICE_API: "api-fxpractice.oanda.com"
  PRACTICE_ACCESS_TOKEN: "xxx-yyy"
  DEFAULT_ACCOUNT_ID: "xxx-xxx-xxxxxxxx-xxx"
  PORT: 443

Thx Kieran now it works fine!

Is it possible to see all orders opened/close in backtest as a report ? Actually I can see only summary statistical info and backtest graph, there's no way to check if strategy works as expected by inspecting a report trade by trade.

Glad to hear.

Absolutely, you can access all of this info via at.trade_results - this is an instance of the TradeAnalysis class.

To look at the trades (ie. fills), you can inspect at.trade_results.trade_history, giving you a DataFrame like this:

In [5]: at.trade_results.trade_history
Out[5]: 
                                         order_time  order_price order_type                 fill_time  fill_price  direction     size  fee instrument  id  order_id  broker
2022-01-19 11:00:00+00:00 2022-01-19 10:00:00+00:00     1.061250     market 2022-01-19 11:00:00+00:00     1.06120          1  3663.00  0.0    AUD_NZD   1         1  broker
2022-01-20 00:00:00+00:00 2022-01-20 00:00:00+00:00     1.065345     market 2022-01-20 00:00:00+00:00     1.06535         -1  3663.00  0.0    AUD_NZD   2         1  broker

Since you are using Oanda, you might be more interested in at.trade_results.isolated_position_history. This will closer reflect how Oanda manages 'trades', which is a bit more like treating them as positions (hence the name 'isolated position'). This DataFrame looks as so:

In [8]: at.trade_results.isolated_position_history
Out[8]: 
                          instrument  status  ID  order_price                order_time  ...                 exit_time  exit_price  trade_duration  fees  broker
2022-01-19 11:00:00+00:00    AUD_NZD  closed   1      1.06125 2022-01-19 10:00:00+00:00  ... 2022-01-20 00:00:00+00:00     1.06535         46800.0  None  broker
2022-01-24 21:00:00+00:00    AUD_NZD  closed   2      1.06631 2022-01-24 20:00:00+00:00  ... 2022-01-25 08:00:00+00:00     1.07047         39600.0  None  broker

There is a whole lot more info to be found in the TradeAnalysis class stored in at.trade_results - try inspecting at.trade_results.__dict__.keys() to start. Note that if you are running a strategy with multiple trading bots, you can access their specific trade analysis object in the same manner, perhaps first by using the get_bots_deployed method to get the bot. Some pseudo code:

EURUSD_bot = at.get_bots_deployed('EUR_USD')
EURUSD_bot.trade_results

Hope this helps!

Thx so much Kieran, I'll take a look
