Any plans to add more indicator series? #106

Bollinger bands and RSI/MFI would be killer :)

This kind of insight is actually a league above your usual RSI/MFI style indicators, adding those would be like going backward.

@projenix On second thought, you're probably right. I'm very interested to see how effective Bollinger Bands would be on micro-time scales though. Let me know if you have any interest in trying to add that as another series. If not, I'll try to have a go at it myself, although my time is very limited! :)

@hanyoonLDA The Bollinger Bands are fundamentally wrong because they are based on a mathematical fallacy and on an optical illusion: 1 - The mathematical fallacy: BBs are based on the standard deviation and the Sdev is not defined for non-stationary time series. Prices are not stationary, therefore the BB idea is mathematically wrong. 2 - The optical illusion: The BB fool people because when they look at it optically it seems as if the price were keeping inside the bands. The thing is, it IS NOT. if you take any moment in time and mark the bands with horizontal lines you will clearly see that the price doesn't care about them at all, what's happening is that future price will seem to rebound of future BB level and that's not useful to someone (like most) who cannot see the future.

Therefore the BB should be regarded as a strictly retail grade / folkloric tool that does not belong in the arsenal of the serious trader (unless you know what you're doing and are only throwing it at non trending and near stationary market conditions).
