Trend tech..

[goodboy]

I've been putting this one off for a while but since it's tab cleaning week here she goes..

There's a variety of strategies, indicators and algos which serve as trend "detectors" under many guises and, names, themes and jargon. This is the beginning of an attempt to breakdown the noise and look at what existing tech exists and how we can move forward with the most correct methods.

A good thing for most to read first is the standard wikipedia article 😉

Github projects that we would consider tinkering type projects :

• stocktrends uses Renko, PnF, LineBreak
• ZigZag: Python library for identifying the peaks and valleys of a time series.

"Serious" methods we are planning to use or do use in practice:

• Trend Calculus
  • A NEW PINESCRIPT INDICATOR: https://www.tradingview.com/script/ohSdmhS0-TrendCalculus/ 😎 🏄🏼 👍🏼 🥳
  • the original presentation / paper
  • I'm way overdue on a Python implementation deliverable
  • there is an original lua reference implementation
  • an under construction scala/spark implementation which was recently merged
• a multi-trend strat used for futures swing trading which I will be implementing as a piker-native strat soon
  • code for this is currently private and haven't decided on a license yet

"Traditional" indicators used frequently by traders in practice:

• TODO

"Commercial" systems you may have heard of that should get audited:

• trendspider
• activetick
• marketsmith

Much more to come.

Tried out trendspider for the free trial; it's definitely a neat idea.

Big quiffs include:

• no scripting language for backtesting
• super laggy and slow (can barely view any data at once)
• "scanners" are more like screeners and aren't updated in realtime

There's also definitely not any special trend tech hiding within; it's all pretty standard stuff.
