# Analyzing bot data # Analyzing bot data with Jupyter notebooks
You can analyze the results of backtests and trading history easily using Jupyter notebooks. A sample notebook is located at `user_data/notebooks/analysis_example.ipynb`. For usage instructions, see [jupyter.org](https://jupyter.org/documentation). You can analyze the results of backtests and trading history easily using Jupyter notebooks. Sample notebooks are located at `user_data/notebooks/`.
*Pro tip - Don't forget to start a jupyter notbook server from within your conda or venv environment or use [nb_conda_kernels](https://github.com/Anaconda-Platform/nb_conda_kernels)* ## Pro tips
## Example snippets * See [jupyter.org](https://jupyter.org/documentation) for usage instructions.
* Don't forget to start a jupyter notbook server from within your conda or venv environment or use [nb_conda_kernels](https://github.com/Anaconda-Platform/nb_conda_kernels)*
* Copy the example notebook so your changes don't get clobbered with the next freqtrade update.
## Fine print
Some tasks don't work especially well in notebooks. For example, anything using asyncronous exectution is a problem for Jupyter. Also, freqtrade's primary entry point is the shell cli, so using pure python in a notebook bypasses arguments that provide required parameters to functions.
## Recommended workflow
| Task | Tool |
--- | ---
Bot operations | CLI
Repetative tasks | shell scripts
Data analysis & visualization | Notebook
1. Use the CLI to
* download historical data
* run a backtest
* run with real-time data
* export results
1. Collect these actions in shell scripts
* save complicated commands with arguments
* execute mult-step operations
* automate testing strategies and prepareing data for analysis
1. Use a notebook to
* import data
* munge and plot to generate insights
## Example utility snippets for Jupyter notebooks
### Change directory to root
Jupyter notebooks execute from the notebook directory. The following snippet searches for the project root, so relative paths remain consistant.
```python
# Change directory
# Modify this cell to insure that the output shows the correct path.
# Define all paths relative to the project root shown in the cell output
import os
from pathlib import Path
project_root = "somedir/freqtrade"
i=0
try:
os.chdirdir(project_root)
assert Path('LICENSE').is_file()
except:
while i<4 and (not Path('LICENSE').is_file()):
os.chdir(Path(Path.cwd(), '../'))
i+=1
project_root = Path.cwd()
print(Path.cwd())
```
### Watch project for changes to code
This scans the project for changes to code before Jupyter runs cells.
```python
# Reloads local code changes
%load_ext autoreload
%autoreload 2
```
## Load existing objects into a Jupyter notebook
These examples assume that you have already generated data using the cli. These examples will allow you to drill deeper into your results, and perform analysis which otherwise would make the output very difficult to digest due to information overload.
### Load backtest results into a pandas dataframe ### Load backtest results into a pandas dataframe
```python ```python
from freqtrade.data.btanalysis import load_backtest_data
# Load backtest results # Load backtest results
from freqtrade.data.btanalysis import load_backtest_data
df = load_backtest_data("user_data/backtest_data/backtest-result.json") df = load_backtest_data("user_data/backtest_data/backtest-result.json")
# Show value-counts per pair # Show value-counts per pair
df.groupby("pair")["sell_reason"].value_counts() df.groupby("pair")["sell_reason"].value_counts()
``` ```
This will allow you to drill deeper into your backtest results, and perform analysis which otherwise would make the regular backtest-output very difficult to digest due to information overload.

### Load exchange data to a pandas dataframe
This loads candle data to a dataframe
```python
# Load data using values passed to function

data_location = Path('user_data', 'data', 'bitrex')

# Confirm success
print("Loaded " + str(len(candles)) + f" rows of data for {pair} from {data_location}")
display(candles.head())
