# Your rules (https://docs.helico.site/docs/your-rules)

Seven things you decide once. Each one stops something.

## The seven rules
| Rule             | What it means                                        | What it stops                           |
| ---------------- | ---------------------------------------------------- | --------------------------------------- |
| Which market     | the one market your funds may be in                  | your funds going anywhere else          |
| How wide         | how wide the band around the price is                | a band wider or narrower than you said  |
| Worth the move   | how much closer a move must bring the band           | churning for no reason, which costs you |
| How often        | at most one move per this much time                  | churning your funds                     |
| How much at once | a cap on how much one move may touch                 | moving more than you allowed            |
| Until when       | the date your rules expire                           | anything after that date                |
| How much to keep | the share of your funds every move must keep working | a move that leaves your funds idle      |

And one more the contract adds by itself: **the new band must contain the current price**. A
band around the wrong price would earn nothing.

> **warn:** "How much to keep" is your protection. Set it to zero and a move is allowed to keep almost
nothing working. Ninety percent is a sensible floor.

## Changing your mind
You can update your rules on the same funds at any time. To switch to a different market, end
the first one yourself, then set new rules. Nothing is ever dropped quietly.

## One market at a time
Each wallet can automate one market at a time. If you have funds in several markets, Helico
manages one of them. This is a real limit and it is written down on purpose.

## Ending it
Withdraw the permission you gave, or press revoke. Either ends everything immediately, and
nothing can block it. Not the program, not us, not a pending update to the contract.
