Moving Average Auto-Adjusted By Timeframe For ThinkOrSwim

[magnetar513]

Someone has probably already done this, but here is my attempt: It seems to work pretty well, but if anyone finds ways to improve it, please let me know.

# Multi Day Moving Average that remains accurate for different chart
# aggregation periods. i.e. Study length is automatically adjusted
# according to aggregation period of the chart.
# I tried adding multiple MAs to a single study, but plotting was
# unreliable, particularly on aggregation periods less than two hours.
# Selecting several single studies with different day lengths on the same chart seems to sidestep these problems.
# Of course, it won't work with Ticks.

What does this do? Doesn't ToS already auto adjust the time frame when you switch between them? I'm not sure what you're script is designed to do.

It allows the moving day averages to remain consistent while using different aggregation periods. Moving average lengths are assigned, by default, as periods, or candles, not days, so a "10 period moving average" doesn't necessarily mean "10 day moving average".

Hi, and great script. I'm attempting to use this, however it won't plot. I've tried to view it on a few different chart timeframes and it won't show on any. Any ideas?

look in the top left corner of chart. is there a white circle with a ! in it? click on it.
there is a max limit of 2000 historical bars.

try a bigger chart time, like hour
(288* numDays) , 288 x 10 = 2880 bars

Thanks for calling it a "great script", but it might not be if it's not working for you. I copied the code onto my system and it seems to work, but for smaller timeframes the plot may be outside the price range shown on the screen. You could try switching to a day aggregation, or select "fit studies" under the "price axis" tab under chart settings. Thanks for the feedback.

Try this script, it's leaner and should be more reliable:


# Multi Day Moving Average accurate for different chart
# aggregation periods.
# Of course, it won't work with Ticks.
