How come plots disappear ?

[grd974]

1) I have this code which works fine :

protected override void OnBarUpdate()
{
if (Time[0].Ticks >= startTime.Ticks && allHours > 0 && startBarIndex == 0)
startBarIndex = CurrentBar;
if (startBarIndex > 0 && startBarIndex == CurrentBar)
DrawDiamond("Start Tag", 0, High[0] + TickSize, Color.Turquoise);
AskTrades.Set((double) AskCount);
BidTrades.Set((double) BidCount);
if (AskTrades[0] > (BidTrades[0]*3.5) && BidTrades[1] > (AskTrades[1]*3.5))
{
PlaySound(@"E:\type.wav");
Print("Ask > 3.5 Bid : " + AskTrades[0]);
}
else if (BidTrades[0] > (AskTrades[0]*3.5) && AskTrades[1] > (BidTrades[1]*3.5))
{
PlaySound(@"E:\online.wav");
Print("Bid > 3.5 Ask : " + BidTrades[0]);
};
if (Close[0] > (prevBidTradePrice+0.5) && prevBidTradePrice != 0)
{
if (DateTime.Now.TimeOfDay.Ticks > (LastUpTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Up>0.50: " + Close[0], @"E:\Pluck2_Up.wav", 0, Color.Lime, Color.Black);
LastUpTime = DateTime.Now.TimeOfDay.Ticks;
}
}
else if (Close[0] < (prevAskTradePrice-0.5) && prevAskTradePrice != 0)
{
if (DateTime.Now.TimeOfDay.Ticks > (LastDnTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Dn>0.50: " + Close[0], @"E:\Pluck_Dn.wav", 0, Color.Crimson, Color.Black);
LastDnTime = DateTime.Now.TimeOfDay.Ticks;
}
};
}

2) as soon as I add the 8 latest lines below, I no longer get both AskTrades and BidTrades plotted :

protected override void OnBarUpdate()
{
if (Time[0].Ticks >= startTime.Ticks && allHours > 0 && startBarIndex == 0)
startBarIndex = CurrentBar;
if (startBarIndex > 0 && startBarIndex == CurrentBar)
DrawDiamond("Start Tag", 0, High[0] + TickSize, Color.Turquoise);
AskTrades.Set((double) AskCount);
BidTrades.Set((double) BidCount);
if (AskTrades[0] > (BidTrades[0]*3.5) && BidTrades[1] > (AskTrades[1]*3.5))
{
PlaySound(@"E:\type.wav");
Print("Ask > 3.5 Bid : " + AskTrades[0]);
}
else if (BidTrades[0] > (AskTrades[0]*3.5) && AskTrades[1] > (BidTrades[1]*3.5))
{
PlaySound(@"E:\online.wav");
Print("Bid > 3.5 Ask : " + BidTrades[0]);
};
if (Close[0] > (prevBidTradePrice+0.5) && prevBidTradePrice != 0)
{
if (DateTime.Now.TimeOfDay.Ticks > (LastUpTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Up>0.50: " + Close[0], @"E:\Pluck2_Up.wav", 0, Color.Lime, Color.Black);
LastUpTime = DateTime.Now.TimeOfDay.Ticks;
}
}
else if (Close[0] < (prevAskTradePrice-0.5) && prevAskTradePrice != 0)
{
if (DateTime.Now.TimeOfDay.Ticks > (LastDnTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Dn>0.50: " + Close[0], @"E:\Pluck_Dn.wav", 0, Color.Crimson, Color.Black);
LastDnTime = DateTime.Now.TimeOfDay.Ticks;
}
};
// est-ce le prix s'envole ?
if (Close[0] > Close[1] && (Close[1] > Close[2] || Close[1] > Close[3]))
{
if (DateTime.Now.TimeOfDay.Ticks > (LastUpTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Up>>: " + Close[0], @"E:\Conn_1250.wav", 0, Color.PaleGreen, Color.Black);
LastUpTime = DateTime.Now.TimeOfDay.Ticks;
}
}
// <<<
if (Close[0] < Close[1] && (Close[1] < Close[2] || Close[1] < Close[3]))
{
if (DateTime.Now.TimeOfDay.Ticks > (LastDnTime + 10000000))
{
Alert(DateTime.Now.Millisecond.ToString(), NinjaTrader.Cbi.Priority.Medium, "Dn<<: " + Close[0], @"E:\Conn_100.wav", 0, Color.LightPink, Color.Black);
LastDnTime = DateTime.Now.TimeOfDay.Ticks;
}
};
// >>>
}

You are going to have to debug your code.
