Curriculum·S210 Automation Literacy: What Bots Actually Do·about 31 min

The unifying insight

By the end of this lesson you can

  • State the single property every automated strategy shares, and derive its consequences
  • Identify which market state a given bot is betting on, from its rules alone
  • Explain why a bot cannot detect the regime it is wrong in
  • Predict a strategy's failure mode before deploying it, rather than discovering it

This lesson opens with The grid that did exactly what it was told.

What happened
During the deleveraging of 10 October 2025, more than $19B of leveraged positions were forcibly closed across more than 1.6 million traders, with roughly 85 to 90 percent of liquidated positions reported to be longs. Futures-based grid strategies were among the clearest failure points. Spot grid strategies could not be liquidated, because no borrowed capital is involved, and instead executed their rules as designed: continuing to place buy orders into a sustained decline and finishing the episode holding the full intended position at an average cost far above the prevailing market. Neither outcome required any component to fail.
The decision point
A grid is a rule that buys declines and sells rallies. A sustained trend is therefore not an edge case for it; it is the condition under which the rule is exactly wrong, in every increment, with increasing size. And the rule contains nothing capable of noticing this, because a rule that could tell which regime it was in would not need to be a grid.

What you will be able to answer

  • What property does every automated strategy share?
  • Which state does a grid bet on, and how does it fail?
  • Why can a bot not detect the regime it is wrong in?
  • How do you predict a strategy's failure mode?

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested

S203-04 owns the three-state taxonomy and the regime classification argument. This lesson applies it to automation. Keep the split.

The claim that spot grid strategies accumulate the asset in a decline is a property of the mechanism rather than an empirical finding about any particular deployment. Present it as derivable from the rules, which it is.
