Steps:

Actual result: Validation error

Expected result: successfully placed order

Note: May be the result of https://github.com/ExchangeUnion/xud/pull/2006

@raladev Can you show the output of lndbtc-lncli channelbalance or lndbtc-lncli listchannels ?

Closed, my mistake, i misused max buy instead of max sell. Checking works correctly.
