Just wondering if you've made any progress with the painfully slow back testing with new spreadsheets. I also notice significant differences between back test results and replay results. Attached is a Trade Activity Log from a spreadsheet system for trading. I have data loaded from 2/16/2017 to 3/17/2017. First I ran an Autotrade System Replay Back Test for all the data, then I ran Replay from as close to the beginning of the chart as I could get. The trades at the end of the activity log from 2/16/2017 to 2/24/2017 (created by the Replay) are much different from the results for those same days at the beginning of the log (from Autotrade System Replay Back Test). I changed nothing in the spreadsheet or the chart. Results like this combined with the back testing taking 3 to 6 times as long as with the old spreadsheets make it impossible for me to use the new spreadsheets.
