If I'm understanding your question correctly, the answer is... you can't. I had several 100% accurate backtests using various intervals (without the detect intrabar = 1 min option selected). And the strategies were built based on what I could see on the chart. Like when I look at a day chart, I can visually tell when the sto is in the right position for the day and the MACDh has crossed 0 that day, etc.... but in real life, tick by tick, those things don't all happen at the same time, so they are never triggered as your eye sees them. Does that answer your question/make sense?
