I need to update about
1.Rate on 17-08-16
Mizuho bank sport rate for T/T USD34.87 YEN.3454
Bangkok bank rate T/T USD34.77 YEN.3489 and can deduct about .03 satang per time because we are good customer(34.74 and 0.3486)
And for point we can request for rate USD same Bangkok bank Mizuho bank they advise must be check time to time because check they market rate at time.
2. if we book forward rate.
We must be increase into at date. Example today we must book rate 34.87 and we will use to pay the next week (within 7 days) we must increase for premium rate 34.90 or will pay within 3 month 34.92(estimate 1 week-month .03 stang,2-3 month .05 stang)
