# Orderflow data
This guide walks you through utilizing public trade data for advanced orderflow analysis in Freqtrade.
!!! Warning "Experimental Feature"
The orderflow feature is currently in beta and may be subject to changes in future releases. Please report any issues or feedback on the [Freqtrade GitHub repository](https://github.com/freqtrade/freqtrade/issues).
!!! Warning "Performance"
Orderflow requires raw trades data. This data is rather large, and can cause a slow initial startup, when freqtrade needs to download the trades data for the last X candles. Additionally, enabling this feature will cause increased memory usage. Please ensure to have sufficient resources available.
## Getting Started
### Enable Public Trades
In your `config.json` file, set the `use_public_trades` option to true under the `exchange` section.
```json
"exchange": {
...
"use_public_trades": true,
}
```
### Configure Orderflow Processing
Define your desired settings for orderflow processing within the orderflow section of config.json. Here, you can adjust factors like:
- `cache_size`: How many previous orderflow candles are saved into cache instead of calculated every new candle
- `max_candles`: Filter how many candles would you like to get trades data for.
- `scale`: This controls the price bin size for the footprint chart.
- `stacked_imbalance_range`: Defines the minimum consecutive imbalanced price levels required for consideration.
- `imbalance_volume`: Filters out imbalances with volume below this threshold.
- `imbalance_ratio`: Filters out imbalances with a ratio (difference between ask and bid volume) lower than this value.
```json
"orderflow": {
"cache_size": 1000,
"max_candles": 1500,
"scale": 0.5,
"stacked_imbalance_range": 3, // needs at least this amount of imbalance next to each other
"imbalance_volume": 1, // filters out below
"imbalance_ratio": 3 // filters out ratio lower than
},
```
## Downloading Trade Data for Backtesting
To download historical trade data for backtesting, use the --dl-trades flag with the freqtrade download-data command.
```bash
freqtrade download-data -p BTC/USDT:USDT --timerange 20230101- --trading-mode futures --timeframes 5m --dl-trades
```
!!! Warning "Data availability"
Not all exchanges provide public trade data. For supported exchanges, freqtrade will warn you if public trade data is not available if you start downloading data with the `--dl-trades` flag.
## Accessing Orderflow Data
Once activated, several new columns become available in your dataframe:
``` python
dataframe["trades"] # Contains information about each individual trade.
dataframe["orderflow"] # Represents a footprint chart dict (see below)
dataframe["imbalances"] # Contains information about imbalances in the order flow.
dataframe["bid"] # Total bid volume
dataframe["ask"] # Total ask volume
dataframe["delta"] # Difference between ask and bid volume.
dataframe["min_delta"] # Minimum delta within the candle
dataframe["max_delta"] # Maximum delta within the candle
dataframe["total_trades"] # Total number of trades
dataframe["stacked_imbalances_bid"] # Price level of stacked bid imbalance
dataframe["stacked_imbalances_ask"] # Price level of stacked ask imbalance
```
You can access these columns in your strategy code for further analysis. Here's an example:
``` python
def populate_indicators(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
# Calculating cumulative delta
dataframe["cum_delta"] = cumulative_delta(dataframe["delta"])
# Accessing total trades
total_trades = dataframe["total_trades"]
...
def cumulative_delta(delta: Series):
cumdelta = delta.cumsum()
return cumdelta
```
### Footprint chart (`dataframe["orderflow"]`)
This column provides a detailed breakdown of buy and sell orders at different price levels, offering valuable insights into order flow dynamics. The `scale` parameter in your configuration determines the price bin size for this representation
The `orderflow` column contains a dict with the following structure:
``` output
{
"price": {
"bid_amount": 0.0,
"ask_amount": 0.0,
"bid": 0,
"ask": 0,
"delta": 0.0,
"total_volume": 0.0,
"total_trades": 0
}
}
```
#### Orderflow column explanation
- key: Price bin - binned at `scale` intervals
- `bid_amount`: Total volume bought at each price level.
- `ask_amount`: Total volume sold at each price level.
- `bid`: Number of buy orders at each price level.
- `ask`: Number of sell orders at each price level.
- `delta`: Difference between ask and bid volume at each price level.
- `total_volume`: Total volume (ask amount + bid amount) at each price level.
- `total_trades`: Total number of trades (ask + bid) at each price level.
By leveraging these features, you can gain valuable insights into market sentiment and potential trading opportunities based on order flow analysis.
### Raw trades data (`dataframe["trades"]`)
List with the individual trades that occurred during the candle. This data can be used for more granular analysis of order flow dynamics.
Each individual entry contains a dict with the following keys:
- `timestamp`: Timestamp of the trade.
- `date`: Date of the trade.
- `price`: Price of the trade.
- `amount`: Volume of the trade.
- `side`: Buy or sell.
- `id`: Unique identifier for the trade.
- `cost`: Total cost of the trade (price * amount).
### Imbalances (`dataframe["imbalances"]`)
This column provides a dict with information about imbalances in the order flow. An imbalance occurs when there is a significant difference between the ask and bid volume at a given price level.
Each row looks as follows - with price as index, and the corresponding bid and ask imbalance values as columns
``` output
{
"price": {
"bid_imbalance": False,
"ask_imbalance": False
}
}
```

You can use whatever naming convention you want, freqtrade1 and 2 are arbitrary. Note, that you will need to use different database files, port mappings and telegram configurations for each instance, as mentioned above.
## Use a different database system
Freqtrade is using SQLAlchemy, which supports multiple different database systems. As such, a multitude of database systems should be supported.
Freqtrade does not depend or install any additional database driver. Please refer to the [SQLAlchemy docs](https://docs.sqlalchemy.org/en/14/core/engines.html#database-urls) on installation instructions for the respective database systems.
The following systems have been tested and are known to work with freqtrade:
* sqlite (default)
* PostgreSQL
* MariaDB
!!! Warning
By using one of the below database systems, you acknowledge that you know how to manage such a system. The freqtrade team will not provide any support with setup or maintenance (or backups) of the below database systems.
### PostgreSQL
Installation:
`pip install psycopg2-binary`
Usage:
`... --db-url postgresql+psycopg2://<username>:<password>@localhost:5432/<database>`
Freqtrade will automatically create the tables necessary upon startup.
If you're running different instances of Freqtrade, you must either setup one database per Instance or use different users / schemas for your connections.
### MariaDB / MySQL
Freqtrade supports MariaDB by using SQLAlchemy, which supports multiple different database systems.
Installation:
`pip install pymysql`
Usage:
`... --db-url mysql+pymysql://<username>:<password>@localhost:3306/<database>`

To save the models generated during a particular backtest so that you can start a live deployment from one of them instead of training a new model, you must set `save_backtest_models` to `True` in the config.
!!! Note
To ensure that the model can be reused, freqAI will call your strategy with a dataframe of length 1.
If your strategy requires more data than this to generate the same features, you can't reuse backtest predictions for live deployment and need to update your `identifier` for each new backtest.
### Backtest live collected predictions
FreqAI allow you to reuse live historic predictions through the backtest parameter `--freqai-backtest-live-models`. This can be useful when you want to reuse predictions generated in dry/run for comparison or other study.

These queries should usually not be necessary as freqtrade tries to handle all database operations itself - or exposes them via API or telegram commands.

You should also **never** run any writing query (`update`, `insert`, `delete`) while a bot is connected to the database.
This can and will lead to data corruption - most likely, without the possibility of recovery.
