Where and how do I collect the daily price information of my steel mesh?

I am an iron and steel employee. In order to ensure the detailed information, the company has nearly 700 information personnel, each of whom is responsible for the special market and quotation, and has long-term contact with the main households in the local market. Information collection channels are as follows:

1, the main way is to consult dealers by telephone (big markets, mostly state-owned enterprises), because market collectors are familiar with these mainstream dealers and can collect the most real prices.

2. Price tables issued by market traders every day; Filtering after removing the false and retaining the true.

3. The ex-factory price of steel mills will also be used as a reference.

I hope it will be useful to you.
