My concept chart 1. one troy ounce is exactly 31.1034768 grams, 2. Thai gold 1 baht = 15.244 grams. Thai gold have relation between XAUUSD and USDTHB but "Thai gold price" was declared from "Gold Traders Associations" (goldtraders.or.th/DailyPrices.aspx) . It have some different price from calculation method , step of price , fee , political ,market in Thai and ... Blahh Blahh . price unit is Thai bath per grams.
after I compare chart , It have many wicks on chart like this link I change price so testing in Daily with Line chart. Price in range 20,200 - 20,900. It have potential down below 20,200 in middle term.
