Follow the steps below:
Open an M1 chart
Press the "F2" key to load History Center
Navigate to the currency pair and the "1 Minute (M1)" history data for the chart you have open in your terminal (be sure to "double click" the "1 Minute (M1)" selection in the history center so it becomes the active selection)
Then left-click once on any of the data rows in the right-hand window of the History Center (it doesn't matter which one)
Click the "Add" button, this pops up another window titled "Bar" and the default selection is on the "year"
Enter 1970
Then select "OK"... and it creates a new bar with the timestamp and price info you just added.
Now select "Close" in the History Center
Attached a script located under "Scripts" folder (with v2v_dynamic_system.zip) >>> Attached this to your chart: ForceLoadHistoricalData.ex4
Navigate to your M1 chart of interest and then from the terminal window (press Ctrl-T) select "Journal "-> go to main chart window and right-click mouse button and select "Refresh"...this will refresh the chart and attempts to fill any time gaps in the chart data (which now includes your year 1970 data point) with server data
Step 10 continued...Now your chart will have pulled anywhere from 2048 to 65536 M1 bars from your broker's server (not Metaquotes server) and is usually far more data than you can get the broker to cough up when you try and manually scroll your M1 chart back in time.
