Minimum Spread

Info on minimum spread


Released on version 0.28.0

This parameter allows Hummingbot to cancel the active order right away when its spread dips below the specified value.

minimum_spread

If the spread of any active order fall below this param value, it will be automatically cancelled.

Prompt:

At what minimum spread should the bot automatically cancel orders?

How It Works

The strategy checks the active order's spread on every tick (1 second).

By default this is set to -100 setting this parameter to a negative value disables this feature. To enable, run config minimum_spread command in the Hummingbot client and specify your minimum spread value.

This only applies to active orders and does not affect hanging orders.

Sample Configuration

- bid_spread : 0.50
- ask_spread : 0.50
- minimum_spread : 0.49
- order_refresh_time : 60.0

With the above configuration, the bot creates buy and sell orders at 0.5% spread from mid price.

00:28:31 - Creating 1 ask orders at (Size, Price): ['0.05 ETH, 229.69USDC']
00:28:31 - Created LIMIT_MAKER BUY order x-XEKWYICX-BEHUC1593217711001924 for 0.05000000 ETHUSDC.
00:28:31 - Created LIMIT_MAKER SELL order x-XEKWYICX-SEHUC1593217711002203 for 0.05000000 ETHUSDC.
Orders:

       1  sell 229.69  0.49%          0.05          0.05  00:00:00
       1   buy 227.41  0.50%          0.05          0.05  00:00:00

Even before the 60 seconds refresh time was up, the sell order was cancelled when its spread went below the minimum.

00:28:40 - Order is below minimum spread (0.0049). Cancelling Order: (Sell) ID - x-XEKWYICX-SEHUC1593217711002203
