Choosing the Right Broker as an Active Trader
Brokerage costs are one of the few variables in trading that you can control completely. Picking the wrong broker can drag your account by 2-4% per month in fees alone, turning a profitable strategy into a breakeven one. Picking the right broker saves you thousands per year and gives you the tools to execute properly.
This article compares the five brokers most commonly used by Australian swing traders: CommSec, Selfwealth, Stake, CMC Markets, and Interactive Brokers. The comparison focuses on what matters for someone making 8-20 round-trip trades per month on positions typically between $2,000 and $15,000.
CommSec
Brokerage (CDIA settlement, online):
- Up to $1,000: $5.00

- $10,001 - $25,000: $29.95
- Over $25,000: 0.12%
Pros:

Cons:

- IRESS comes at an additional monthly cost ($55/month for CommSec Pro)
- The fee structure punishes frequent trading -- 10 round trips at $5,000 each costs $399/month

- Instant funding via Apple Pay and Google Pay
- Switching between ASX and US markets is smooth
- Stake Black ($20/month or $204/year) removes some fees and adds features

- Research and screening tools are minimal -- you will need a separate platform for analysis
- No margin lending
- No options or CFD trading
- The 0.55% FX fee on US trades adds up for international positions

Monthly Cost Calculation: 10 Round Trips
Here is what 10 round-trip trades (20 individual trades) cost per month at three different position sizes:
Position Size: $3,000
| Broker | Fee per trade | Monthly cost | Annual cost |
|---|---|---|---|
| Stake | $3.00 | $60 | $720 |
| IBKR | $6.00 | $120 | $1,440 |
| Selfwealth | $9.50 | $190 | $2,280 |
| CMC Markets | $11.00 | $220 | $2,640 |
| CommSec | $10.00 | $200 | $2,400 |
Position Size: $7,000
| Broker | Fee per trade | Monthly cost | Annual cost |
|---|---|---|---|
| Stake | $3.00 | $60 | $720 |
| IBKR | $6.00 | $120 | $1,440 |
| Selfwealth | $9.50 | $190 | $2,280 |
| CMC Markets | $11.00 | $220 | $2,640 |
| CommSec | $19.95 | $399 | $4,788 |
Position Size: $15,000
| Broker | Fee per trade | Monthly cost | Annual cost |
|---|---|---|---|
| Stake | $3.00 | $60 | $720 |
| IBKR | $12.00 | $240 | $2,880 |
| Selfwealth | $9.50 | $190 | $2,280 |
| CMC Markets | $15.00 | $300 | $3,600 |
| CommSec | $29.95 | $599 | $7,188 |
The numbers speak clearly. At 10 round trips per month, Stake saves you between $1,560 and $6,468 per year compared to CommSec, depending on position size. On a $30,000 account, CommSec's annual brokerage drag ranges from 8% to 24% of the account, while Stake sits at 2.4%.
Recommendation by Trader Type
Cost-focused beginner with a small account ($5,000-$15,000) Stake. The $3 flat fee means your brokerage costs are negligible relative to your account size. You will need TradingView or another free charting platform for technical analysis, but the savings far outweigh the inconvenience.
Intermediate trader who values simplicity ($15,000-$50,000) Selfwealth. The $9.50 flat fee is still competitive, the platform is more capable than Stake, and the flat-fee structure means costs are predictable regardless of position size.
Active trader who needs charting and screening tools ($20,000+) CMC Markets. The built-in charting and screening tools eliminate the need for a separate analysis platform. At $11 per trade, fees are moderate, and the free international trading is a bonus if you trade US stocks.
Trader who wants the most complete platform and does not mind paying for it ($50,000+) CommSec with IRESS. If your account is large enough that brokerage is a small percentage of your capital, CommSec's research, tools, and CBA integration are hard to match. The IRESS platform provides Level 2 data and advanced order types that other retail platforms lack.
International trader who needs multi-market access Interactive Brokers. No other Australian-accessible broker comes close for international market access and low international brokerage. The trade-off is the lack of CHESS sponsorship and a steeper learning curve.
