Hi, there is a handy site where you can check the movement of the currency pair(e.g. usd-thb, eur-thb, gbp-thb, aud-thb, thb-jpy) at a glance.
check out on google as follows:
1-investing.com currency historical data usd-thb(or eur-thb, gbp-thb, aud-thb, jpy-thb)
2-Register that site as Your Favorite on your pc/phone/tablet.
Then you can see the movement of the currency pair of your interest straight away.
