FlowAlgo is a US-based subscription service that scans stock and equity options markets in real time and surfaces institutional-sized order activity for individual traders. Its core feed tracks intermarket sweep orders (large orders routed across multiple exchanges simultaneously to fill quickly), option block trades (privately negotiated large options trades), and equity and dark pool block prints, presenting them on a live dashboard with alerts that can be filtered by ticker and date range. The company describes itself explicitly as a data provider rather than a stock-picks alert service, meaning it surfaces the raw order flow and leaves interpretation to the subscriber. The product is built for traders who already understand options mechanics rather than beginners: independent reviews consistently note a steep learning curve, since FlowAlgo displays unfiltered institutional flow without built-in guidance on strikes, expirations, Greeks, or whether a given trade is a hedge or a directional bet. It differentiates itself from competing options-flow tools through its "Levels" module, which converts accumulated flow data into support, resistance, and accumulation/distribution zones, and through a historical flow database, since the live dashboard itself only retains same-day activity. Every subscription tier bundles the same feature set, including a trader chatroom and voice alerts, rather than gating features by plan. FlowAlgo was founded in 2017 and is based in Huntington Beach, California. Company-data aggregator Tracxn lists it as unfunded, with no external venture rounds reported, consistent with it operating purely on subscription revenue. Pricing runs on a monthly, quarterly, or annual cycle, currently advertised as a two-week trial for 37 dollars followed by a 149 to 199 dollar monthly rate, discounted to roughly 129 dollars a month on a quarterly plan and 99 dollars a month on an annual plan.
