The standard deviation formula is based on a year's worth of data. If we do not have a year's worth of data, we do not compute the standard deviation.
If you want a standard deviation for one of these stocks, look at the volatility, or the average true range, instead. These are similar, but they look at shorter time frames. Almost every stock has a 15 minute volatility. (There are some exceptions. Many people would be surprised to know there are a lot more stocks out there that don't trade every day than do, and a lot move around all day by a small fraction of a penny.) The average true range Configuration Window: Average True Range requires 3 weeks of daily data.
This is a common policy at Trade-Ideas. If a formula (like ATR or standard deviation) requires a certain amount of data, and we don't have that much data, we don't compute the formula. If you ask the see the value, it will be blank. If you use that value in a filter, you will filter out any stocks where we could not compute the value. This works on intraday and daily formulas. We are a little bit more liberal on the daily formulas. If a stock did not trade one day, we look back further until it did trade. Intraday, we don't allow any missing candles in the middle of the formula.
