If you want to go long:
Once the price stops at 635.05 or 623.12 support, a long entry may be better if a bounce is confirmed from there.
Target: 651 / 667+
Stop loss: 620 or below.
If you want to go short:
If the price closes below 635, it will be a bearish confirmation.
Short entry below 635, target 623 / 597
Stop loss: 645+
