Below are well‑suited stockbroker options and selection tips for working (full‑time) individuals in Sri Lanka — i.e., people who need easy online/mobile access, low‑friction account opening, reasonable fees, good customer support and useful research/alerts.

Top Sri Lanka brokers to consider (good for busy/working investors)

• John Keells Stock Brokers — large, well‑established, good research and an online/mobile trading app (suitable if you value trusted brand + research). (jksb.com)
• Capital Alliance Securities — active trading member with online services and retail offerings; commonly recommended among CSE trading members. (cdsvapt.efuturesworld.com)
• Nestor Stock Brokers — established retail and institutional broking with an online presence and ATrad connectivity. Good for investors who want a long‑standing local firm. (nestorstockbrokers.lk)
• First Guardian Equities — trading member with full services and online access; known to serve retail clients as well as institutional. (cdsvapt.efuturesworld.com)
• JB (J B) Securities / Asia Capital Stock Brokers / Senfin / Richard Pieris Securities — reputable local trading members that appear on CSE/CDS participant lists; suitable choices if they offer a good mobile platform and local customer support. (Check each firm’s mobile trading features). (es.scribd.com)
• ATrad (trading platform) — not a broker but a widely used real‑time online trading/analytics platform used by many Sri Lankan brokers; if your chosen broker uses ATrad you’ll get a robust mobile/web experience for trading on the CSE. Good sign for working investors who need reliable mobile access. (ATrad.lk)

If you want easy access to international markets (US/NASDAQ, ETFs) from Sri Lanka

• Interactive Brokers and other international brokers (MEXEM, CapTrader, XTB, etc.) are popular for low fees and wide market access — useful if you want to trade US stocks/ETFs during non‑Sri Lanka hours or want one account for global investing. These are not CSE members; they serve Sri Lankan residents for foreign markets. (brokerchooser.com)

How to pick the best broker for a working person (quick checklist)

• Mobile/web app quality: must support real‑time quotes, order entry, alerts and simple fund transfers (look for demo/screenshots). A broker using ATrad or a modern native app is a plus. (ATrad.lk)
• Account opening speed and documentation: choose one that supports digital/onboarding or has straightforward local branches if you prefer in‑person help. (jksb.com)
• Fees & minimums: compare brokerage per‑trade, any platform/inactivity fees, and payment/withdrawal costs. For small, regular investments cost per trade matters more. (brokerchooser.com)
• Research & alerts: if you have limited time, pick a broker that provides morning commentaries, curated watchlists, price alerts or periodic research notes. Larger firms (John Keells, Capital Alliance) often offer stronger research. (jksb.com)
• Customer support hours: ensure support availability outside strict market hours (or at least quick help during trading hours) so problems can be resolved quickly. (ATrad.lk)

Practical next steps (fast)

1. Shortlist 2–3 brokers from above.
2. Compare: mobile app reviews/screenshots, brokerage per trade, account opening steps, and whether they use ATrad or another real‑time platform. (ATrad partner brokers usually advertise that.) (ATrad.lk)
3. Check that the broker is a licensed CSE/SEC trading member (CSE/CDS participant lists). (cds.lk)
4. Open a demo or basic account and test placing one small trade to learn the app and settlement/funding flow.

If you’d like, I can:

• compare fees and apps for 3 specific brokers you’re considering, or
• show which brokers use ATrad (so you get the same mobile experience) — tell me 2–3 names you’re weighing and I’ll pull direct fee/app comparisons and cite sources.

(Notes: I focused on brokers that are members of the Colombo Stock Exchange or widely used platforms for Sri Lankan investors and on international brokers commonly used from Sri Lanka. If you want strictly local‑only options or strictly global brokers, tell me which and I’ll tailor the shortlist and fetch the latest fee/feature comparisons.)
