Botcrypto does not impose minimum volumes on bots.

However, in real, we depend on trading platforms that apply minimum volumes on orders. You can check these limits here :
Limits on Binance
Limits on Kraken

If you get the following error Binance request failed: Filter failure: MIN_NOTIONAL, it means that the bot is trying to pass an order with a value that is too low for Binance.
