CheckLastBidirectionalTradeThreshHold *bool    `json:"check_last_bidirectional_trade_thresh_hold,omitempty"`

example of configuration that want to swap KMD/LTC with 1.5% spread, maximum available balance, 1/4 to be filled,
and a price validity of 30 seconds (that means that order will be cancelled if the last update from the price service is above 30 seconds), with 1 confirmations and without notarization. Check trade history with local mm2 DB to never sell < average trading price.
