Internal bulletin boards extend reciprocity by letting traders broadcast local market observations

Evidence

More reciprocity is accomplished through internal bulletin boards, which were progressively implemented by GB1 and other banks for specific financial instruments (e.g., spot or option trading) from 1996–97 onward. Internal bulletin boards allowed the dealers in this instrument to post what they saw in their local environments and to list some deals, so that others in the bank could pay attention to them. — Karin Knorr Cetina & Urs Bruegger, Global Microstructures, 81
