Below the toys, there are shelves stocked with small items, possibly keychains or small trinkets. The front of the kiosk displays images of ice cream cones and bottles of beverages, suggesting that it might also sell refreshments. The setting appears to be a park or a fair, with trees and a fence v…

Breaking the Trend: How to Avoid Cherry-Picked Signals
Our empirical results, illustrated in Fig.5, show an impressive fit with the pretty complex theoritical Sharpe formula of a Trend following strategy depending on the parameter of the signal, which was derived by Grebenkov and Serror (2014). That empirical fit convinces us that a mean-reversion process with only one time scale is enough to model, in a pretty precise way, the reality of the trend-following mechanism at the average scale of CTAs and as a consequence, using only one simple EMA, app…

If you set limits for a scale (e.g. x-axis) in ggplot, how would you like data outside of that range be handled? There is the oob parameter for that and a set of functions to use with it: scales.r-lib.org/reference/oob

Out of bounds handling — oob
This set of functions modify data values outside a given range. The oob_*() functions are designed to be passed as the oob argument of ggplot2 continuous and binned scales, with oob_discard being an exception. These functions affect out of bounds values in the following ways: oob_censor() replaces out of bounds values with NAs. This is the default oob argument for continuous scales. oob_censor_any() acts like oob_censor(), but also replaces infinite values with NAs. oob_squish() replaces out of…
