This is my indicator: return average[10] coloured(255,0,0,255) as "sma10",average[50] coloured(0,0,255,255) AS "sma50" and this is my strategy: buy at -close limit GraphOnPrice average[10] coloured(255,0,0,255) as "sma10" GraphOnPrice average[50] coloured(0,0,255,255) as "sma50" The two SMA’s are plotted differently by ProOrder, compared to those plotted by ProBuilder, from Friday May 31st, 2019 01:00am up to: Sma10 till Monday June 3rd,2019 00:45am Sma50 till Monday June 3rd,2019 04:05am (that’s 40 more bars, the period difference beteween 50 and 10, on DAX, 5-minute TF) It seems ProOrder stops calculating them at some point. Any known reason why?
