Plot renders into the future

[Chillionaire]

I have the following script. Not really much to it to be honest, just 2 lines. Define a moving average variable and then plot that variable indexed to the prior bar. Moves the plot forward in time instead of actually rendering the plot on the current candle.

def avg = SimpleMovingAvg(close, 20);
def avgHist = avg[1];

plot Data = avg;
plot Data2 = avgHist;

This plot shifts forward one candle into the future instead of stopping on the current candle. Bizarre.
Any ideas why that is happening?

screen shot of the result shows the purple plot has jumped ahead of the current candle.

it plots because the variable has valid data at that time location.
there are placeholders for candles after the last visible candle.

after the last bar, 2 of the plots are visible because they are looking back at previous bars, so they have valid data.
plot D4 = round(avg[1],2);
plot D5 = round(avg[2],2);


here is a test study that draws 5 lines, each with a different offset.

# test_lines_offset1

def avg = SimpleMovingAvg(close, 20);
#def avgHist = avg[1];
#plot Data2 = avgHist;


plot D1 = round(avg[-2],2);
plot D2 = round(avg[-1],2);
plot D3 = round(avg[0],2);
plot D4 = round(avg[1],2);
plot D5 = round(avg[2],2);

addchartbubble(1, low,
d1 + "  [-2]\n" +
d2 + "  [-1]\n" +
d3 + "  [0]\n" +
d4 + "  [1]\n" +
d5 + "  [2]" 
, color.yellow, no);

Thank you so much. That explanation makes perfect sense. So at least now I know that the data in my calculations for the current candle is ok, even though the next candle's values are already plotting.

I'm guessing there is no way to disable this behavior, so I'll just ignore it.

Thanks again,

This will help keep the plot within the display of active candles.

def avg = SimpleMovingAvg(close, 20);
def avgHist = avg[1];

plot Data = avg;
plot Data2 = if isnan(close) then double.nan else avgHist;
