[RESEARCH] Custom Median vs Built-in Median

I compared custom median (using the sorting solution by @apozdnyakov) with built-in median (using percentile_nearest_rank function)

If you see the zero line this means the solutions give the same results.

The best results was achieved on the odd lengths.

Conclusions:

1) Do not try to reinvent the wheel.

2) Always check the Pine Script docs to find already implemented solutions.
