History Orders are marked by arrows, which reflects order Open Price, Stop Loss, Take Profit, Close time and price. Each order is on markets active chart, just limit is, you can see only correspondenting history orders to your selected trade instrument.

To run this script, please, close your MetaTrader 4 and put OrderHistory.mq4 in your MQL4\Scripts directory, then restart your MetaTrader 4. After it appears under scripts list you may use it. Just a notice though, it does not delete own placed arrows so it's best to work on clear chart. By the way, use smallest intervals with large history for best arrows fitting.
