Hello, i just tested both programms with IB´s datafeed for stock trading and noticed that it takes minutes to load a 1m chart in NT. This is an experience others had too on this forum. In Quantshare the charts get loaded instantaneously. Because of this problems a user of NT is forced to use an additonal datafeed (kinetick, barchart etc.) which causes a lot of costs. I like NT´s charting more but this is a fact which could be the deciding factor for Quantshare. In know also tradingview and tc 2000 but they are not connected to IB, so you cannot trade.
