Hey there guys. do you think it is possible to code this indi for FX (MT4)? Beta is used to assess the volatility of an instrument.
In stocks trading the beta is calculated by comparing a stock to a index. Since we don't have a broad market index in FX (Well, we have the US Dollar Index at least), I don't know how if this would work, but it is worth a try.
Here is what I found:
A much better idea is to construct a market average of currencies, making sure to adjust them for their dollar values, then compare them by standard deviation.
By calculating beta in this way, it is possible to find the currencies that are trading with the highest volatility compared to the rest. In this way:
Beta (EURUSD) = StdDev (EURUSD) / StdDev (market average)
