# Mechanics of analyzing micro fluctuation

This is not financial advice. Do your own research before investing. Note, for those coming from reddit, this is a copy and paste of the post on Reddit.

When I create a grid bot, I try to choose an asset that fluctuates the most. Long term trend is important, too, but I care more about how violently the price fluctuates about some mean value. We can look at charts, EMA, Bollinger Bands, etc. and try to visually determine this, or we can do some basic quantitative analysis. Maybe there’s an indicator for these sort of stuff, but how I do it is, I take the 6 hour closing price of an asset (which I fetch from Binance database) and compute the fluctuation about the mean.

I can go into the technical details, but basically I use a technique called a Savitzky-Golay filter from signal processing field to smooth out the fluctuation (parameters are chosen empirically and I don’t want to go into too much details here). I then subtract this filtered price from the original price, and divide the difference by the filtered price.

When you do that, you get a plot that looks like the below (ETH-USDT for example):

On the top figure, red is the filtered “smooth” price, and the blue is the actual 6 hr closing price obtained from Binance. The bottom figure shows essentially the difference between the blue and red curve, divided by the red curve (and then multiplied by 100 to convert it into percent). I did this analysis for the assets (in USDT) I can find via Binance candle stick client data (I hope Pionex will eventually provide a public API to allow access to their exchange data, directly). I compute the variance of the fluctuation over the past month and get the following (in increasing order):

Note, the ranking next to the pair name (“th”) is the market cap ranking according to the coinmarketcap API. As you can see, busd and paxg are the least fluctuant (obviously, since they’re both pegged to USD). BTC is a big boy so it doesn’t fluctuate much either. The most fluctuant are smaller cap coins like ONE and CHR. No surprise here, but at least you won’t have to rely on your “gut feelings” and “intuitions” when choosing the asset.

Obviously, you don’t want to invest in dog s**t coins so don’t just go off by the fluctuation %, but also look at trade volumes (liquidity) and longer term prospect as well.

In the next blog entry, I might talk about how to compute the Pearson correlation across assets and how to use that information as a strategy to predict the next pumping coin. I’ll probably post here first, then post on reddit.
