Ordinance No. 1On Green Candles
Whensoever a chart runs green for more than three minutes together, the buy window shall be shut, the citizen being plainly in danger of making money.
Sheriff’s Office · Notice No. 1
Hear ye, hear ye. Robin Hood's old enemy has taken the badge, pinned it to your broker, and appointed himself your protector. Whensoever the trade finally turns good, Sheriff Hood shall slam the vault door shut, smiling the whole while, for your own protection.
Buy's closed, partner. — S. Hood, $SHERIFF
Exhibit A
A demonstration of the Sheriff's protection, for the public's education. Reach for the button. Nothing is bought here; nothing ever gets the chance.
The window is open. For now.
Posted by order of the Sheriff
Read aloud each dawn by Deputy Margin, shortly before he helps shut the door.
Whensoever a chart runs green for more than three minutes together, the buy window shall be shut, the citizen being plainly in danger of making money.
Deputy Margin shall ring the opening bell at sunup, with great ceremony, and shall assist in slamming the vault door no later than a few minutes thereafter. The bell is for morale.
Any townsfolk found holding a winning position after dark shall have said position escorted to the vault for safekeeping. Receipts are not issued.
The sell window stays open at all hours, day and night. The Sheriff is generous like that.
Gentlemen in top hats behind the vault door may cheer as loud as they please whenever it slams. Cheering from outside the vault constitutes loitering.
All grievances may be filed in person at the Sheriff's office, which is closed. For your protection.
Roster of the Office

Badge No. 001
Sheriff · Head of Customer Protection
Stout, smug, and grinning under a green ten-gallon hat, with a crooked tin star on his vest and the vault key on his belt. He has never once locked the door without smiling.

Badge No. 002
Deputy · Bell Ringer, Door Pusher
Jittery, eager, always early. Rings the opening bell like his life depends on it, then shoulders the vault door shut a few minutes later and apologises to nobody.

No badge required
Behind the door · Cheering section
A shadowy gang of fat cats in top hats who live on the far side of the vault door. Every time it slams shut, you can hear them through four feet of steel.

Keep this ticket. The Sheriff won't.
