the filter will probably expect a timezone , that is a massive headache to resolve so get the news in gmt and turn to server time on "download"

To turn the gmt times to Time of the server you will need to have an input that receives the offset or try to synchronize when the ea is live.

Meaning when a tick is received (so market is live + broker is alive) you can pull a snapshot of the TimeCurrent and the TimeGMT and find the offset .

Your problem will then be weekends . So , for a given week you must store the time difference discovered live , or , update it everytime a new bar forms .

TimeCurrent() and TimeTradeServer() functions MT5 how to get Broker/Server Timezone

you are looking to extract this part ?

Alain Verleyen 2023.07.10 21:24 #8

A lot of complication for nothing, all these information can be obtained directly from MQL and available data.
