Agora Market update - Conditional commands

The trading game in all items is now starting for real!

You can now use bids and asks to trigger another commands, for cool effects in the marketplace. Syntax is simple: just use ">" sign in the command to indicate that when the preceding part is fully executed, the next part takes effect.

Examples:

1. Buy, sell, and make a quick buck

BUY MEAT 1000 3000>SELL MEAT 1000 3500

Meat spoils only slowly and has liquid markets. It is quite possible that if you place this order, someone dumps you meat, and then the system puts them automatically for sale, and when you check again, the logs tell you that you both bought and sold the meat (while offline) and just have more money.

2. Sell, buy, and make a quick buck

SELL MEAT 1000 3500>BUY MEAT 1000 3000

Same as before, but if you first have the meat and want to buy back lower later.

3. Stop loss

BUY S-CKG 1 6500>SELL S-CKG 1000 1

Places first a small buy order below CKG's current price, so that if someone dumps to it, it triggers your dump at market price.

4. FOMO

SELL S-CKG 1 7500>BUY HM02B100 10 100000000

A small ask in S-CKG is placed to trigger a market buy in gold bars. If the price reaches target, then it's better not be left behind.

5. Cross-asset class arbitrage

SELL CON 50 20000000>BUY 8-N 1 1000000000

After careful examination, I decided that land at 1,000 mil per chapelry yields more than CON at 20 mil per unit. This buys the land right after the CON is sold fully.

6. Automatic increase of gold stock as shares are sold to the market

SELL S-CKG 10000 7000>BUY HM02B100 1 70000000


The simple but powerful new feature allows market making in many items by anyone. There has been an idea to make the speculative gold market to happen in S-CKG instead of the 10,000 times bigger HM02B100 bars. We are confident that the change is technically possible to happen and would allow:
1. Gold ownership (by proxy) for everyone, due to the small unit size (7,000 m)
2. Tighter spreads in market making, down to 1% from current 3%
3. Every action by players causes an instant addition of opposite side orders, keeping the spread thin in active market conditions.

FEATURE SHOULD WORK ALREADY
