Fund Builder

Describe a theme in a few words. The Tuatara vector model surfaces the stocks or cryptocurrencies with hidden relationships to it — supply-chain, structural and financial links that keyword search and generic AI miss — and turns them into a fund you own and can trade.

Theme

A few words — “data centre electricity”, “drone warfare”.

Connections

Tuatara surfaces the non-obvious supply-chain, structural and financial links.

Review

You see every name it found and why, before anything is weighted.

Live

A price-weighted index with its own trading terminal.

Self-directed AIB

Build your own AIB — pick every asset yourself

Add, select or deselect any stocks, cryptos or perps we support — you choose every holding directly. Your fund gets a real-time price-weighted index and its own trading terminal; you can edit the membership any time. Community funds trade in paper mode (simulated) — no real USDC is invested.

Fund name

Add an asset — stocks (Brokerage100), crypto or perps

Symbol	Name	Type

No assets yet — add at least 2 to create a fund (up to 30).

Your fund always mints price-weighted — one share per leg, so each holding's starting allocation follows its live price, not a percentage you pick here.

Advanced — algorithms, filters & TA indicators (optional)

Rebalance weighting preference (does not affect initial mint — see below)

Every self-directed fund mints price-weighted (one share per leg). This selection only records your preference for a later, owner-approved rebalance — it does not change today's allocation.

Technical indicators — drives the model's proposals (you approve every change)

Buy signal (optional) — e.g. rsi_14 < 30 and macd_hist > 0

Sell signal (optional) — e.g. rsi_14 > 70

Screener filters (optional) — a candidate below any floor is never added

This basket has crypto or perp legs — you can run it long or short and (optionally) deploy a managed perp sleeve on the managed perp venue funded from your own balance.

The managed sleeve stays off until you fund it and the managed-trading rail is available — no platform funds are ever used.

Step 01 · Theme

Describe your theme

Two or three words is usually enough.

Stock funds activate instantly during US market hours. Outside them they queue and go live at the next open.

Up to five prompts, each measured separately — the strongest signals win. Singular terms read the network best: “satellite”, not “satellites”. Expect surprising names. The point is what is connected, not what is obvious.
