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

Interface illustration of Preload — laid out from the real on-chart board; money values are shown as dashes.

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

  1. Attach it to any chart

    One spare chart is enough.

  2. Wait for the panel

    Let it run until the panel reports every pair complete.

  3. 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?
