There might be several reason on why this happen:
- Your balance is below the min. purchase amount in stocks, which is set at Rp 5.000
- You order outside of market hour (20.30-03.00 WIB). If this is the case, then it means that your buy order is already successful, you just need to wait for market to open so that it is realized.
