I would like to ask whether there is a good way of analysing stock indicators that have no value limitations. For indicators like RSI we have a closed range ( 0 - 100 ) but in case of indicators like for example OBV we may have two stocks that have 10000000 and 1000 value of this indicator respectively in the same period of time. Does it make sense to discretize values of such indicators, by creating the same range (for example from 0 to 100) for each stock or it is completely senseless?
Technical analysis is not quite in my wheelhouse, but it's been an interesting topic to me, so hopefully I can lend a hand. Let's start with some basic assumptions: Because OBV is based on volume, there is obviously a huge range as you've pointed out. This makes comparison straight across companies impossible.
To compare companies, you need to take out certain factors that could affect volume. My first inclination would be to adjust for the size of a company. Common markers of size would be revenue (REV) and market cap (MKCAP). I wouldn't have much hesitancy in using size as an adjustment for any company data.
Thinking through it a bit more, because OBV is often seen as an indicator of how "smart money" is moving in an economy, you might want to adjust for price, as small investors will be slow to buy really expensive stocks and quicker to buy cheaper stocks. You may want to rethink this for other indicators, but it is an option.
Looking at these two options I'd be more inclined to adjust an indicator for size. This way you can look at companies across a range of sizes and sectors. This might work better for some indicators and worse for other. I don't know how well these would work but it has sparked some interest for me, hopefully it helps you find what you're looking for!
