Hello, mate. Since I have personally been using the OANDA platform to trade for more than a year, I can vouch for its security. Since I've never experienced any issues with transactions or transfers with it, I believe it may be regarded as safe. Additionally, it offers you the chance to open an Oanda demo account https://tradersunion.com/brokers/forex/view/oanda/oanda-demo-account/ and practice virtual trading so that you can learn how it works without risking your own money.
