dealer_net

Shares brokerage dealers bought minus what they sold for their own book (自營商). The smallest of the three and largely hedging, so read it beside the other two rather than alone.

foreign_net

Shares foreign and mainland institutions bought minus what they sold (外陸資). The biggest single force in Taiwanese equities, and the one that moves in and out fastest.

institutional_net

Shares the three institutional groups bought minus what they sold (三大法人). Positive is accumulation, negative is distribution — and unlike turnover, this can cross zero.

trust_net

Shares domestic Taiwanese investment trusts bought minus what they sold (投信). Local fund money, slower to turn than the foreign flow and often on the other side of it.

The money that changed hands in this name that day — price times shares, not a share count.
