Starting a stock brokerage firm means assembling a specific stack: the technology to offer equities, access to market pricing and liquidity, a system to manage clients and risk, and the setup required for the markets you serve. Equities behave differently from forex and CFDs, so an equities launch has its own considerations, but the underlying logic is the same one that governs any brokerage launch: proven technology, reliable liquidity, and a client layer that converts and retains.
