SQL Helper¶
This page contains some help if you want to edit your sqlite db.
Install sqlite3¶
Sqlite3 is a terminal based sqlite application. Feel free to use a visual Database editor like SqliteBrowser if you feel more comfortable with that.
Ubuntu/Debian installation¶
bash
sudo apt-get install sqlite3
Using sqlite3 via docker-compose¶
The freqtrade docker image does contain sqlite3, so you can edit the database without having to install anything on the host system.
bash
docker-compose exec freqtrade /bin/bash
sqlite3 <database-file>.sqlite
Open the DB¶
bash
sqlite3
.open <filepath>
Table structure¶
List tables¶
bash
.tables
Display table structure¶
bash
.schema <table_name>
Get all trades in the table¶
sql
SELECT * FROM trades;
Fix trade still open after a manual sell on the exchange¶
Warning
Manually selling a pair on the exchange will not be detected by the bot and it will try to sell anyway. Whenever possible, forcesell
It is strongly advised to backup your database file before making any manual changes.
Note
This should not be necessary after /forcesell, as forcesell orders are closed automatically by the bot on the next iteration.
sql
UPDATE trades
SET is_open=0,
close_date=<close_date>,
close_rate=<close_rate>,
close_profit = close_rate / open_rate - 1,
close_profit_abs = (amount * <close_rate> * (1 - fee_close) - (amount * (open_rate * (1 - fee_open)))),
sell_reason=<sell_reason>
WHERE id=<trade_ID_to_update>;
Example¶
sql
UPDATE trades
SET is_open=0,
close_date='2020-06-20 03:08:45.103418',
close_rate=0.19638016,
close_profit=0.0496,
close_profit_abs = (amount * 0.19638016 * (1 - fee_close) - (amount * (open_rate * (1 - fee_open)))),
sell_reason='force_sell'
WHERE id=31;
Remove trade from the database¶
Use RPC Methods to delete trades
Consider using /delete <tradeid> via telegram or rest API. That's the recommended way to deleting trades.
If you'd still like to remove a trade from the database directly, you can use the below query.
sql
DELETE FROM trades WHERE id = <tradeid>;
sql
DELETE FROM trades WHERE id = 31;
Warning
This will remove this trade from the database. Please make sure you got the correct id and NEVER run this query without the where clause.
Use a different database system¶
Warning
By using one of the below database systems, you acknowledge that you know how to manage such a system. Freqtrade will not provide any support with setup or maintenance (or backups) of the below database systems.
PostgreSQL¶
Freqtrade supports PostgreSQL by using SQLAlchemy, which supports multiple different database systems.
Installation:
pip install psycopg2
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>
