So my ideas the other day did not activated which was just fine.
We'd rather have un activated and expired orders than the activated and loss order.
Now let's do another try for M15 time frame, the pending orders are as followed:
Buy Stop @ 1799
TP @ 1806
SL @ 1796
Sell Stop @ 1795
TP @ 1788
SL @ 1798
Set Expiration time/ waiting time: 4 hours from now, apply to both orders.
After 4 hours from now if none of them activated they'll be cancel automatically.
REMEMBER: When one pending order is activated, cancel the remained pending manually and immediately.
Merry Christmas.
