I have been hesitating a lot to post a request for support as I know you are very busy these days with all the new plans. But I'll give it a try at last. I have developed a strategy for automated trading, using the spreadsheet. When backtesting it gives great results. However, forward testing gives completely different results. I am not talking slippage and spread here. But it triggers much more trades in forward testing (live data) and not profitable, using the same algo. To give you an idea: Forward testing yesterday on the ES resulted in a profit factor 0.52 (8 trades, of which 3 profitable) Doing a backtest of yesterday resulted in just 1 profitable trade. Same product (ES), same algo, everything the same. I am using 2 times frames for the algorithm. Please advice if you have a chance. Thank you in advance. additional explanation: There are 3 tabs in my chartbook: 1st tab: Main Chart (TF M25), with referenced chart (TF M5) below the main chart (using Study/Price overlay) 2nd tab: the referenced chart 3th tab: spreadsheet with the Buy and Sell algo etc. I have also noticed this: If For All Charts in Chartbook (in replay window) is enabled, results of backtesting is miserable If For All Charts in Chartbook (in replay window) is disabled, results of backtesting are very good So my question also is how do I get forward / live testing with good results? Where is it refering to, if it is not to the second chart? Where are those good results coming from? Date Time Of Last Edit: 2013-06-25 20:47:08

You have to enable For all Charts in Chartbook or the value referenced on the higher time frame chart will be the close value on the higher time frame chart and not the value that existed in real time on the lower time frame chart. In other words your results will be better because your strategy is in essence looking into the future. If you run a bar based backtest, then I think you will have the same type of issue. If you simply plot a higher time frame on a lower time frame and manually walk through the chart you will have the same issue as well.
