Description
Although you can request multiple markets from listMarketBook, /wiki/spaces/BFAPIBETA/pages/1212460 and listMarketProfitandLoss, there are limits on the amount of data requested in one request.
sum(Weight) * number market ids must not exceed 200 points
The following tables explain the "weighting" of data for each MarketProjection or PriceProjection. If you exceed the maximum weighting of 200 points, the API will return a TOO_MUCH_DATA error.
