SL Cap Mngt Equity chart

SL Cap Mngt system: Zoom on equity chart shows major drawdown recently from $140K Oct 15 to $132K - $127K range (upper - lower line). Closed trades since Oct 15 = <$5483> ttl. loss. From $140K peak that implies approx $134,500 current equity; a higher value than equity line(s). Open positions from Oct 8 add to +$7276. Can anybody make sense of this? Whats the upper versus lower boundry of green equity line? Is Open equity displayed? Sorry if Q’s are dumb. MH in Toronto. [LINKSYSTEM_47004256]
