inquiry Regarding Historical Data Alert in EA Testing

[Quener Ando Medalla]

Hello everyone,

I hope this message finds you well.

I am encountering an issue while testing my EA today, and I'm hoping to get some insights. Yesterday, everything was running smoothly, but today I'm receiving the following alert:

```

2024.03.01 09:46:07.550 Tester EURUSD: no history data from 2019.01.01 00:00 to 2024.02.26 00:00

```

I'm curious about why this alert is appearing suddenly. Could anyone help me understand the possible reasons behind this and suggest any solutions?

Your assistance is greatly appreciated.

Thank you,

Ner

If it is MT5 so go to View - Symbols - ... and so on (Bars, Ticks), and load the data. And/or open the chart of EURUSD starting from M1 timeframem right mouse click on the chart and and "Refresh", after that - M5 timeframe and so on up to W1.
There are several easy ways to load the history, for example: you can just open the chart(s) for every timeframe.

If your Metatraderis MT4 so there is one summary post:

Do not forget to set the chart settings (in MT5),

and do not forget to connect your Metatrader to trading account (demo or live/real).

I do not know.
In case of MT5 - the data/quotes/prices are realted to the brokers only.

My example: I am selecting the broker for some/my criteria: walking distance office in my city + good data/quotes/prices.
