1. China A50 already went down
2. When SET50 opens, it gap down.
So there is a high probability it will go down again
(based on past history, based on SET50 behaviour/personality/characteristics ....)
3. SET50 went down from point 1 to 2.
Then retrace from 2 to 3.
4. After point 3 (price 882.6), be on high alert.
For SET50, my max loss is around 12 to 15 ticks.
5. enter immediately when the price goes to 881.4
6. Place STOP at 882.6 + 2 or 3 ticks = 882.9
7. So, the max loss for this case is 882.9 - 881.4 = 15 ticks
