### SELL Order
```
(set max position=$1000,
spread=$10, QQQ etf price(Qetf)=$100. ),
then the quote u give is:
Bid Ask
10shares@$95 10shares@$105
($1000 of Qetf). ($1000 of Qetf)
if a trader hit ur ASK by bidding 2 shares of QQQ token ,then the output quote:
Bid. Ask
10shares@$95 8shares@$105
($1000 of Qetf). ($800 of Qetf)
if another trader hit ur ASK with a 20 shares of bid , then only 8 shares of his order can be filled.
u dont need to handle his remaining 12 shares , its not ur responsibility, its his "broker/app/program" to deal with unfilled order.
so ur quote becomes
Bid. Ask
10shares@$95
($1000 of Qetf).
SELL 10 SHARES OF "QQQ_TOKEN"
FOR CURRENT_PRICE( "CryptoExchange", "QQQ_TOKEN" ) + 5 USD
WITH LIMIT OF 1000 USD
FROM "CryptoExchange"
```
### BUY Order
```
BUY 10 SHARES OF "QQQ_TOKEN"
FOR CURRENT_PRICE( "CryptoExchange", "QQQ_TOKEN" ) - 5 USD
WITH LIMIT OF 1000 USD
FROM "CryptoExchange"
```
### BUY Trigger for above
```
BUY 1 SHARES OF "QQQ"
FOR CURRENT_PRICE( "StockExchange", "QQQ" )
FROM "StockExchange"
FOR EVERY 1 SHARES OF "QQQ_TOKEN" SOLD FROM "CryptoExchange"
```
```
