Based on my points of view:
Rule 4-9-18 by plotting trend line shown that YTL share price will going to reverse to downtrend.
For those who still making profit and have not sell YTL, better to sell now as more than 5 times history repeat itself shown that RM1.70 share price failed to breakout. Share price will going to drop if break below RM1.70.
Support level: RM1.70
Resistance level: RM1.80
