If I have an instrument that trades on some exchange and I am not getting its data, then I get the use of a symbol map to receive the data.All good.
But, say I have an instrument, say ES. Now I create a duplicate instrument, and say I call it ES1. The Master instrument name is different but the symbol map is the same as that of ES. If I try to create a chart with the symbol ES1 I get an error: "Unknown instrument ES1".
My question is...What do you mean unknown instrument? I provided you with a symbol map.
It therefore appears to me that NT doesn't really make any use of the symbol mapping and somehow just looks for the symbol on the exchange.If it did use the mapping then this error would not occur. So, what's the point of the map?
