Use this setting to tell bot to completely close positions when martingale hits certain level for a particular pair . When condition is met, bot will close ALL positions for that pair regardless of how much your negative positions at the time. The idea is to limit account from suffering further and bigger losses. This works on pair-by-pair basis.
Bot will then stay shut down for that pair for X number of hours as specified in ShutDownOnMartingaleLengthHours.
