Preload
Warms the D1/W1 history for 28 pairs — run it once on a new install
- MetaTrader 5 v1.2.1 Released
The on-chart board
Multi-symbol boards read D1 and W1 series for symbols other than their own chart, and MetaTrader serves none of it until the symbol is synchronised — so on a fresh install the board sits half-grey for a long time. Preload pulls the history those boards need in one pass, shows its progress on the chart, and places no orders at all.
What it does
- Downloads the D1 and W1 history for the 28 pairs the boards use
- Shows a progress panel on the chart and tells you when it is done
- Resumes after an interruption by asking the terminal what it actually holds
- Places no orders and reads no account state
How it works
-
Attach it to any chart
One spare chart is enough.
-
Wait for the panel
Let it run until the panel reports every pair complete.
-
Remove it
Then detach the EA and open the board you actually want.
Who it suits
- Anyone on a fresh MetaTrader 5 install or a new broker
- Anyone whose board keeps showing grey cells
What to watch out for
- A data-preparation utility — it has nothing to do with trading results.
- Speed depends on your broker's history server and the terminal's "Max bars in chart" setting.
Questions about Preload
Do I need to run it every day?
