If I’m using MT4, then its a case of drawing vertical lines to help assist location of the trade, it is a pain, and I do a lot of strategy development work so I ended up writing an application that would allow me to display and simultaneously scroll though multiple charts.
When I first started to get serious abut backtesing I used to store details of trades (both live and backtest) in an external database. I allocated each trade a unique ID, way back when I was using MT3 for back testing and I developed a custom indicator that can read trades from the database, and then mark them on the charts, applying appropriate color codes etc. It saves a lot of time, particularly if your undertaking analysis across multiple timeframes.
I’ve seen similar indicators on a few forums that can do the same thing taking the trade history directly from MT4, it only takes a few lines of code, so its probably easier to write someting from scratch rather than modifying somone elses code.
