Yes — and it's one of the most natural things to automate, because rebalancing is already a rule: when the mix drifts from target, trade back to target. No judgment calls, no forecasts. Automation matters here because rebalancing always feels wrong in the moment — it means selling whatever everyone is celebrating.
Why is rebalancing such a natural fit for automation?
Because it's already an algorithm, even when a human runs it by hand. Rebalancing needs three things: the current weights of your portfolio (measurable), a condition ("has anything drifted more than X points from target?"), and an action ("trade back to target"). There is no forecasting, no news interpretation, no judgment call anywhere in the loop — every step is arithmetic. That makes it different from, say, deciding which coins deserve to be in the portfolio at all, which genuinely requires human thinking. A rule that a computer can check every minute without getting bored, greedy, or scared is a rule a computer should probably be running.
Why do humans keep botching something this simple?
Because rebalancing always tells you to do the thing that feels wrong. By definition, it sells whatever has been going up — the position everyone, including you, is excited about — and buys more of whatever has been disappointing. Concretely: if a 70/30 portfolio drifts to 85/15 during a rally, the rule says sell a chunk of the asset that has been winning for months. Every instinct screams "let it ride." The reverse is worse: after a crash, the rule says buy the thing that just fell, using your safe stablecoins. People who rebalance manually tend to skip precisely the rebalances that matter most, because those are the ones that feel most wrong. Software doesn't feel anything.
How do you actually set up an automated rebalancing rule?
Three decisions, made once, in calm conditions:
| Setting | What it controls | Example |
|---|---|---|
| Target weights | The mix being maintained | 70% BTC / 30% stablecoins |
| Trigger | When the bot acts | Drift beyond ±5 points, or a monthly date |
| Minimum trade size | Skips dust trades that only pay fees | Ignore drifts worth less than $50 |
The band and the minimum matter more than they look. Too tight a band and the bot churns, paying fees to correct noise; too loose and it barely differs from doing nothing. Set them, then let the rule run through at least one full market mood swing before judging it — a rule that only ever saw a rally hasn't been tested yet.
