IDX Lowers Auto-Rejection Limit to 7% from Today

The Indonesia Stock Exchange (IDX) has amended the auto-rejection limits in the regular and cash markets. The rule takes effect today, Monday, 19 October 2026.

The amendment refers to IDX Regulation II-A on the Trading of Equity Securities. Under the new provisions, the exchange is introducing asymmetric auto-rejection limits.

The upper auto-rejection limits remain unchanged, while the lower limit is standardised at 7% for all price brackets above Rp10. Previously, the lower limit for those brackets was 15%.

For shares priced from Rp1 to Rp10, both the upper and lower auto-rejection limits remain Rp1, as before.

For shares priced from Rp11 to Rp200 inclusive, the upper limit remains 35%, while the lower limit falls from 15% to 7%.

For shares priced above Rp200 up to Rp5,000 inclusive, the upper limit remains 25% and the lower limit falls from 15% to 7%.

For shares priced above Rp5,000, the upper limit remains 20%, while the lower limit also falls from 15% to 7%.

The change therefore applies only to price declines. A share’s fall in a single trading day is now capped more tightly at 7%, while the scope for price increases remains as before.

The IDX said the asymmetric auto-rejection policy would apply from 19 October 2026 to 31 December 2026.

“The asymmetric auto-rejection limits policy applies from 19 October 2026 to 31 December 2026 and will be reviewed in line with developments in market conditions,” the IDX said in an official statement on Monday, 19 October 2026.

The exchange also said the policy would be reviewed in response to market developments, and that the provisions could change following the review.

The IDX reiterated its commitment to good corporate governance. All IDX personnel are prohibited from accepting gratification in any form, in accordance with the applicable rules.
