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.

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.
