(Adds BSE's share move; updates moves)
** Shares of Indian brokerages drop 1%-5%
** India's markets regulator proposes raising minimum
trading amount for index options by more than three times,
reducing the number of contracts expiring each week and a rise
in trading margins
** Exchanges and retail-focused brokers will be most
impacted, says Jefferies
** However, Jefferies says exchange operator BSE BSEL.NS
may offset this impact, and may also gain if volumes spill over
from discontinued products to those which are continued
** BSE gains 7% after opening 1.5% lower
** Angel One ANGO.NS fell as much as 2.4% in early trade
before paring all losses to trade 1.7% higher
** Investec expects 30% drop in derivatives orders per
client for ANGO; sees it raising prices to 25 rupees per order
from 20 rupees
** SMC Global Securities SMCG.NS drops 4.5%, the most
among brokers, followed by Dolat Algotech's DOLA.NS 2.5% and
Geojit Financial Services' GEOJ.NS 1.4% decline, respectively
