"""
NOTE: We can't use multiple inheritance in Python because this is a managed class. We will use composition instead so in
order to call the methods of SetupBaseStructure we'll call then using self.setup.methodName().
----------------------------------------------------------------------------------------------------------------------------------------
The base class for all the alpha models. It is used to setup the base structure of the algorithm and to run the strategies.
This class has some configuration capabilities that can be used to setup the strategies more easily by just changing the
configuration parameters.
Here are the default values for the configuration parameters:
scheduleStartTime: time(9, 30, 0)
scheduleStopTime: None
scheduleFrequency: timedelta(minutes = 5)
maxActivePositions: 1
dte: 0
dteWindow: 0
----------------------------------------------------------------------------------------------------------------------------------------
The workflow of the algorithm is the following:
`Update` method gets called every minute
- If the market is closed, the algorithm exits
- If algorithm is warming up, the algorithm exits
- The Scanner class is used to filter the option chain
- If the chain is empty, the algorithm exits
- The CreateInsights method is called
- Inside the GetOrder method is called

This class is used to setup the base structure of the algorithm in the main.py file.
It is used to setup the logger, the timer, the brokerage model, the security initializer, the
option chain filter function and the benchmark.
It is also used to schedule an event to get the underlying price at market open.
The class has chainable methods for Setup and AddUnderlying.
How to use it:
1. Import the class
2. Create an instance of the class in the Initialize method of the algorithm
3. Call the AddUnderlying method to add the underlying and the option chain to the algorithm
Example:

Initialize a backtest. Requires data and a strategy to test.
`data` is a `pd.DataFrame` with columns:
`Open`, `High`, `Low`, `Close`, and (optionally) `Volume`.
If any columns are missing, set them to what you have available,
e.g.
df['Open'] = df['High'] = df['Low'] = df['Close']
The passed data frame can contain additional columns that
can be used by the strategy (e.g. sentiment info).
DataFrame index can be either a datetime index (timestamps)
or a monotonic range index (i.e. a sequence of periods).
`strategy` is a `backtesting.backtesting.Strategy`
_subclass_ (not an instance).
`cash` is the initial cash to start with.
`commission` is the commission ratio. E.g. if your broker's commission
is 1% of trade value, set commission to `0.01`. Note, if you wish to
account for bid-ask spread, you can approximate doing so by increasing
the commission, e.g. set it to `0.0002` for commission-less forex
trading where the average spread is roughly 0.2‰ of asking price.
`margin` is the required margin (ratio) of a leveraged account.
No difference is made between initial and maintenance margins.
To run the backtest using e.g. 50:1 leverge that your broker allows,
set margin to `0.02` (1 / leverage).
If `trade_on_close` is `True`, market orders will be filled
with respect to the current bar's closing price instead of the
next bar's open.
If `hedging` is `True`, allow trades in both directions simultaneously.
If `False`, the opposite-facing orders first close existing trades in
a [FIFO] manner.
If `exclusive_orders` is `True`, each new order auto-closes the previous
trade/position, making at most a single trade (long or short) in effect
at each time.

Optimize strategy parameters to an optimal combination.
Returns result `pd.Series` of the best run.
`maximize` is a string key from the
`backtesting.backtesting.Backtest.run`-returned results series,
or a function that accepts this series object and returns a number;
the higher the better. By default, the method maximizes
Van Tharp's [System Quality Number](https://google.com/search?q=System+Quality+Number).
`method` is the optimization method. Currently two methods are supported:
* `"grid"` which does an exhaustive (or randomized) search over the
cartesian product of parameter combinations, and
* `"skopt"` which finds close-to-optimal strategy parameters using
[model-based optimization], making at most `max_tries` evaluations.
[model-based optimization]: \
https://scikit-optimize.github.io/stable/auto_examples/bayesian-optimization.html
`max_tries` is the maximal number of strategy runs to perform.
If `method="grid"`, this results in randomized grid search.
If `max_tries` is a floating value between (0, 1], this sets the
number of runs to approximately that fraction of full grid space.
Alternatively, if integer, it denotes the absolute maximum number
of evaluations. If unspecified (default), grid search is exhaustive,
whereas for `method="skopt"`, `max_tries` is set to 200.
`constraint` is a function that accepts a dict-like object of
parameters (with values) and returns `True` when the combination
is admissible to test with. By default, any parameters combination
is considered admissible.
If `return_heatmap` is `True`, besides returning the result
series, an additional `pd.Series` is returned with a multiindex
of all admissible parameter combinations, which can be further
inspected or projected onto 2D to plot a heatmap
(see `backtesting.lib.plot_heatmaps()`).
If `return_optimization` is True and `method = 'skopt'`,
in addition to result series (and maybe heatmap), return raw
[`scipy.optimize.OptimizeResult`][OptimizeResult] for further
inspection, e.g. with [scikit-optimize]\
[plotting tools].
[OptimizeResult]: \
https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.OptimizeResult.html
[scikit-optimize]: https://scikit-optimize.github.io
[plotting tools]: https://scikit-optimize.github.io/stable/modules/plots.html
If you want reproducible optimization results, set `random_state`
to a fixed integer random seed.
Additional keyword arguments represent strategy arguments with
list-like collections of possible values. For example, the following
code finds and returns the "best" of the 7 admissible (of the
9 possible) parameter combinations:
backtest.optimize(sma1=[5, 10, 15], sma2=[10, 20, 40],
constraint=lambda p: p.sma1 < p.sma2)

Plot the progression of the last backtest run.
If `results` is provided, it should be a particular result
`pd.Series` such as returned by
`backtesting.backtesting.Backtest.run` or
`backtesting.backtesting.Backtest.optimize`, otherwise the last
run's results are used.
`filename` is the path to save the interactive HTML plot to.
By default, a strategy/parameter-dependent file is created in the
current working directory.
`plot_width` is the width of the plot in pixels. If None (default),
the plot is made to span 100% of browser width. The height is
currently non-adjustable.
If `plot_equity` is `True`, the resulting plot will contain
an equity (initial cash plus assets) graph section. This is the same
as `plot_return` plus initial 100%.
If `plot_return` is `True`, the resulting plot will contain
a cumulative return graph section. This is the same
as `plot_equity` minus initial 100%.
If `plot_pl` is `True`, the resulting plot will contain
a profit/loss (P/L) indicator section.
If `plot_volume` is `True`, the resulting plot will contain
a trade volume section.
If `plot_drawdown` is `True`, the resulting plot will contain
a separate drawdown graph section.
If `plot_trades` is `True`, the stretches between trade entries
and trade exits are marked by hash-marked tractor beams.
If `smooth_equity` is `True`, the equity graph will be
interpolated between fixed points at trade closing times,
unaffected by any interim asset volatility.
If `relative_equity` is `True`, scale and label equity graph axis
with return percent, not absolute cash-equivalent values.
If `superimpose` is `True`, superimpose larger-timeframe candlesticks
over the original candlestick chart. Default downsampling rule is:
monthly for daily data, daily for hourly data, hourly for minute data,
and minute for (sub-)second data.
`superimpose` can also be a valid [Pandas offset string],
such as `'5T'` or `'5min'`, in which case this frequency will be
used to superimpose.
Note, this only works for data with a datetime index.
If `resample` is `True`, the OHLC data is resampled in a way that
makes the upper number of candles for Bokeh to plot limited to 10_000.
This may, in situations of overabundant data,
improve plot's interactive performance and avoid browser's
`Javascript Error: Maximum call stack size exceeded` or similar.
Equity & dropdown curves and individual trades data is,
likewise, [reasonably _aggregated_][TRADES_AGG].
`resample` can also be a [Pandas offset string],
such as `'5T'` or `'5min'`, in which case this frequency will be
used to resample, overriding above numeric limitation.
Note, all this only works for data with a datetime index.
If `reverse_indicators` is `True`, the indicators below the OHLC chart
are plotted in reverse order of declaration.

`agg` is the aggregation function to use on resampled groups of data.
Valid values are anything accepted by `pandas/resample/.agg()`.
Default value for dataframe input is `OHLCV_AGG` dictionary.
Default value for series input is the appropriate entry from `OHLCV_AGG`
if series has a matching name, or otherwise the value `"last"`,
which is suitable for closing prices,
but you might prefer another (e.g. `"max"` for peaks, or similar).
Finally, any `*args` and `**kwargs` that are not already eaten by
implicit `backtesting.backtesting.Strategy.I` call
are passed to `func`.

# Let's convert closing prices back to pandas Series.
close = self.data.Close.s
# Resample to daily resolution. Aggregate groups

daily = close.resample('D', label='right').agg('last')
# We apply SMA(10) to daily close prices,
# then reindex it back to original hourly index,

Abstract method for initializing resources and parameters for the strategy.
This method is called once at the beginning of the backtest to perform any necessary setup or configuration

needed for the strategy's functionality.
Parameters:
- *args: Additional positional arguments that can be passed during initialization.
- **kwargs: Additional keyword arguments that can be passed during initialization.
Example:
```python
def init(self, buy_period: int, sell_period: int):
self.buy_signal = {}
self.sell_signal = {}
for symbol in self.symbols:
self.buy_signal[symbol] = UpBreakout(self.data[(symbol,'Close')], buy_period)
self.sell_signal[symbol] = DownBreakout(self.data[(symbol,'Close')], sell_period)

Parameters:
- i (int): Index of the current time step.
- record (Dict[Hashable, Any]): Dictionary representing the market data at the current time step.
The keys can include symbols, and the values can include relevant market data (e.g., OHLC prices).
