I've been trying to pull TAS data from Reuters TRTH API and GUI both. But I'm only able to get the data from 24 Jan 2019 till Yesterday. I thought we can get the data since the product is listed on an Exchange. Please clarify till how far can we fetch the Time and Sales data for a Product.
Please refer to the image attached as we can clearly see that data for certain fields is missing before 24 Jan 2019. I've tried it for several RICs and several exchanges also, but this is the same result I get for all.
