Hi Kurt The code appears to work fine for me. If you've only tested one or two charts against the explorer for results but not loaded a substantial number of bars for the exploration there's a very good chance that what you get from the explorer will differ from what you see on a chart. There are a couple of reasons for this. The first reason is that the MACD() function needs 100-150 bars loaded to generate a truly accurate result. Why? Because MACD is the difference between two exponential moving averages and EMAs need as much as five times as much data as the Periods parameter of the longer EMA (as a rule of thumb a 26 period EMA needs around 125 periods to deliver the kind of accuracy you probably expect). The second reason you could run into a problem is because of the BarsSince() function in the code. Many MS functions force the Explorer to load sufficient data, as indicated by the longest Period parameter, to get the job done. As I've already said, EMAs don't force sufficient records to load, and this "defect" carries over into RSI(), ADX() and 25 or so other common functions. Then there's another group of functions that don't even use either a regular or a hidden Periods parameter, and BarsSince() falls into this category. Others in the same category are Alert() and any finction using an Nth parameter - ValueWhen(), HighestSince() and so on. My guess is that your problems will simply vanish once you stipulate the loading of at least 150-200 records. For the most part the columns or filter of an exploration function exactly the same as an indicator. What's different is that the reported result only tells you the state of your code as at the last bar of data, and the all-too-frequent failure to load sufficient data for the code to function as intended. Hope this helps. Roy

I tried your way, but still failed even 1000 record bars were loaded...
Please help!

I am quite busy, so I can't explore the market everyday... And my preference is to buy the stocks with MACD crossover. So, I want to find the stocks with MACD crossover within the latest 8 days in order to avoid missing any stocks with MACD crossover recently.
