Version 4 & 5

The 4 and 5 version were published in order to fix ta.crossover/ta.crossunder pinescript functions. Hopefully this will fix any issues in the future and some of you dont get false alerts (even when used with bar close alert type) .

At the same time if you guys want to be even safer, you can use instead of MTF MA Timeframe 30min with 1440 length instead of 1D WITH 30 lenght. They have similar performances.

Lastly I would recommend you to look for assets which been around since last crypto winter and are strongly correlated with btc , such as bch, bnt, btg, dash, etc, eth, fil ,neo, ltc, xlm, zec just to name a few .

Of course you can use the others as well, this will lead to bigger profits, but also bigger risk of manipulaiton/dumps/crashes and resulting in bigger losses.
