Fluxy vs Coinrule
Fluxy vs Coinrule: if-this-then-that vs quant engineering
Coinrule made a real contribution: it turned 'if price drops 3%, buy' into something a non-programmer can automate in minutes, across many exchanges. For simple reactive rules it's a fine tool. The ceiling arrives when your idea stops fitting an if-then sentence — portfolio-level sizing, funding-aware carry, regime filters — and that ceiling is exactly where Fluxy starts.

Side by side
Where the two part ways
| Fluxy Fund | Coinrule | |
|---|---|---|
| Custody | Non-custodial — trade-only keys, withdrawals disabled at the venue | Non-custodial — API-key based |
| Expressiveness | Full Python: portfolio sizing, vol targeting, multi-venue carry, anything you can code | If-this-then-that rule sentences |
| Backtesting realism | No look-ahead by construction, settlement-clock funding, delisting realism | Rule-level testing; varies by plan |
| Portfolio construction | Multi-strategy book with per-strategy tilts and portfolio limits | Per-rule |
| Investor accounting | Unitized NAV, high-water-mark fees, statements — built in | Not a fund-accounting product |
| AI assistance | AI writes real strategies against your actual datasets, validated by backtest | Template suggestions |

The honest verdict
Which one is for you?
Choose Coinrule if your strategy genuinely fits an if-then sentence and you never want to code. Choose Fluxy when the idea outgrows the sentence — and you want the backtest that tells you whether it was a good idea.
