The figures below use the platform's built-in default rates (commission 0.012% both sides with a CNY 5 minimum; stamp duty 0.05% on sells; transfer fee 0.001% both sides; regulatory fees 0). Rates can be overridden by deployment configuration; the order confirmation step is authoritative. The A-share channel is currently unavailable.
Example 1: buy CNY 100,000
Notional 100,000.00 CNY Commission 100,000 × 0.00012 = 12.00 CNY (above the CNY 5 minimum) Stamp duty 0.00 CNY (not levied on buys) Transfer fee 100,000 × 0.00001 = 1.00 CNY ──────────────────────────────────────────── Total 13.00 CNY
Example 2: sell CNY 100,000
Notional 100,000.00 CNY Commission 100,000 × 0.00012 = 12.00 CNY Stamp duty 100,000 × 0.0005 = 50.00 CNY (sell side only) Transfer fee 100,000 × 0.00001 = 1.00 CNY ──────────────────────────────────────────── Total 63.00 CNY
Example 3: buying CNY 10,000 hits the CNY 5 minimum
Notional 10,000.00 CNY Commission 10,000 × 0.00012 = 1.20 CNY → below the minimum Charged 5.00 CNY (per-order minimum) Transfer fee 10,000 × 0.00001 = 0.10 CNY ──────────────────────────────────────────── Total 5.10 CNY
Where the minimum stops binding
| Notional | Commission at rate | Commission charged | Notes |
|---|---|---|---|
| CNY 10,000.00 | CNY 1.20 | CNY 5.00 | Far below the minimum, so CNY 5 applies |
| CNY 41,666.67 | CNY 5.00 | CNY 5.00 | The point where the rate exactly equals the minimum |
| CNY 41,708.33 | CNY 5.00 | CNY 5.00 | Still CNY 5.00 after rounding to the cent, so the minimum still binds |
| CNY 41,708.34 | CNY 5.01 | CNY 5.01 | The first notional that actually pays more than CNY 5.00 |
On small orders the commission minimum dominates the real cost: the CNY 5.10 in example 3 is 0.051% of notional — four times example 1 (0.013%). When one order fills in several parts, the CNY 5 minimum is applied once per order, not once per partial fill.
Example 4: why the limit price is 11.06 and not 11.05
| Previous close | Price limit | Lower limit | Upper limit |
|---|---|---|---|
| CNY 10.05 | ±10% (Main Board) | CNY 9.05 | CNY 11.06 |
| CNY 10.05 | ±20% (ChiNext / STAR) | CNY 8.04 | CNY 12.06 |
| CNY 10.05 | ±30% (Beijing) | CNY 7.04 | CNY 13.07 |
| CNY 10.05 | ±5% (Main Board ST) | CNY 9.55 | CNY 10.55 |
10.05 × 1.1 = CNY 11.055. The exchange rule is to round half-up to the tick size (CNY 0.01), so the upper limit is CNY 11.06; truncating would give 11.05 and an order at 11.06 would be rejected. That one cent decides whether a limit-up order gets in.
