10 min czytaniaTwo Polish Brokers with Different DNA
XTB and Bossa (Biuro Maklerskie BOŚ) are among the most popular Polish brokers, but their market approach is fundamentally different. XTB is a global player, listed on the Warsaw Stock Exchange (WSE), with a strong marketing brand. Bossa is a "quiet gem" — a brokerage house affiliated with Bank Ochrony Środowiska (BOŚ Bank), valued by experienced investors for reliability and unique ETF offerings.
Commissions — Who's Cheaper?
XTB
- Stocks and ETFs (WSE and foreign exchanges): 0% commission up to 100,000 EUR/month turnover, above 0.2% (min. 10 EUR)
- CFD: spread depending on instrument
- Forex: spread from 0.1 pips (Pro accounts)
- No account maintenance fee (with activity or balance)
Bossa
- WSE stocks: 0.29% (min. 5 PLN) — standard brokerage commission
- WSE ETFs: 0.29%
- Foreign ETFs (via Bossa Zagranica): depending on market, typically 0.29% (min. 19 PLN) or flat rate model
- No account maintenance fee
- IKE/IKZE: same commissions as regular account
Verdict: XTB is significantly cheaper for investors buying stocks and ETFs — the 0% commission model (up to limit) is a powerful advantage. Bossa compensates with other aspects.
Instrument Offering
XTB
- Over 3,000 stocks from 16 global exchanges
- Over 700 ETFs
- CFDs on indices, commodities, cryptocurrencies
- Forex
- No access to government bonds (through platform)
- Fractional shares — you can buy a fraction of stock for any amount
Bossa
- WSE and NewConnect stocks
- WSE ETFs (including Polish ETFs on S&P 500, MSCI World, etc.)
- Foreign ETFs — broad access through Bossa Zagranica
- Government and corporate bonds on Catalyst market
- Futures contracts on WSE
- Investment funds (BossaFund)
Bossa has a unique advantage: access to bonds on Catalyst and investment funds in one place. XTB offers a much larger selection of foreign stocks and ETFs with zero commission.

Bossa — bossaWebTrader and NOL3
- bossaWebTrader: browser-based trading platform — functional, though visually modest
- NOL3: professional WSE platform (free for Bossa clients)
- Mobile app: basic, but sufficient for order placement
Verdict: XTB wins decisively in terms of UX and platform modernity. Bossa is more "raw," but NOL3 is a powerful tool for active WSE traders.
IKE and IKZE (Polish Retirement Accounts)
Both brokerage houses offer retirement accounts:
XTB IKE/IKZE
- Access to stocks and ETFs (0% commission within limit)
- No access to bonds
- Simple to open and manage
Bossa IKE/IKZE
- Access to stocks, ETFs, bonds, and funds

Education and Support
XTB

Fund Security

- Bossa: BOŚ Bank brokerage house, regulated by KNF, subject to KDPW
In both cases, client assets are separated from broker assets. In case of broker bankruptcy, your stocks and ETFs are safe — they are registered in KDPW under your name.
