As we understand from the samples, the txt file should be converted to S# format before we can run strategy and testing on them. Please update if this understanding is correct. <br /><br />We need sample code how we can covert txt file to S# format through code. What are the classes we should look at?<br /><br />Or alternatively, can we run strategy on history data stored in txt file directly? Please share sample code if this is possible.<br /><br />Regards<br />Shubha https://stocksharp.com/topic/6962/ 2016-10-26T20:09:38Z 2016-11-02T16:27:08Z Hola1212 https://stocksharp.com/users/95773/ info@stocksharp.com Hello,<br /><br />What is the fastest way to run an Optimization (and backtest) in S#Designer? <br /><br />I ask because the instructions shown here <a href="http://stocksharp.com/forum/6939/Brute-Force-Optimization-in-SDesigner-/#m37163 " title="http://stocksharp.com/forum/6939/Brute-Force-Optimization-in-SDesigner-/#m37163 ">http://stocksharp.com/fo...n-in-SDesigner-/#m37163 </a>seem to require S#Designer to read market data from a .CSV file for each Optimization (rather then importing the data from the .CSV once and converting it to a format machines can read/process faster then a classical .CSV)<br /><br />Perhaps there is a way to use S#Data to convert the .CSV data to a format S#Designer can use to speed up Optimizations (and backtests)? <br /><br />Cheers
