Previous Day Close Moving Averages

Hello can anyone code a script that plots horizontal lines of the previous day closing moving averages for the 5-day EMA, 10-day EMA, 21-day EMA, 50-day SMA, 100-Day SMA and 200-Day SMA that shows at the beginning of the premarket session? I would really appreciate it
 
TOS has a built in study called DailySMA you can apply to a chart multiple times to handle all of your simple averages. Copy their code for that one to a new study and change Average to ExpAverage on line 16 to create the same thing for exponential averages.

Thank You, I was able to find this code, do you know how to modify the code so that the lines from the previous day are connected together?
Ruby:
plot ema5 = expAverage(close(period = aggregationPeriod.DAY)[1],5) ;

plot ema10 = expAverage(close(period = AggregationPeriod.DAY)[1],10);

plot ema21 = expaverage(close(period = AggregationPeriod.DAY)[1],21);

plot sma50 = average(close(period = AggregationPeriod.DAY)[1],50);

plot sma100 = average(close(period = AggregationPeriod.DAY)[1],100);

plot sma200 = average(close(period = AggregationPeriod.DAY)[1],200);



ema5.setPaintingStrategy(paintingStrategy.HORIZONTAL);

ema10.setpaintingStrategy(paintingStrategy.HORIZONTAL);

ema21.setpaintingStrategy(paintingStrategy.HORIZONTAL);

sma50.setpaintingStrategy(paintingStrategy.HORIZONTAL);

sma100.setpaintingStrategy(paintingStrategy.HORIZONTAL);

sma200.setPaintingStrategy(paintingStrategy.HORIZONTAL);

Yes, that code should do what you want. To have no break in the lines between days, remove all of that stuff at the bottom that sets the painting strategy to horizontal.

A downside of having all of this in one study is none of the plots will show on new stocks that don't have 200 days of data yet. That's why I recommended using the the built in study and adding it to the chart for each average length. That way the exponentials always show and each simple shows as soon as it has enough data for its length. The exponentials could be all in one study without having this same problem but not the simples.

You're obviously welcome to do whatever you feel is appropriate for your trading.

For others who may read this thread:
It has nothing to do with the price of the stock. It's based on how long the stock has existed, which has nothing to do with market cap or even how long the company has existed. When large companies merge they often form a new legal entity with a new, though still recognizable, name and trade under a new ticker. There's 220 trading days in a year. With the code above the lines will not show until 200 trading days have passed. Same for any IPO. You may or may not want to trade it in its early days but it'll be almost a year later when your lines finally show up.

@Slippage
Is it possible to change the aggregation period? I tried changing to lower periods but it does not plot. Thank you
