I advise you to learn how to work with signals yourself, this will give a much more positive result. Otherwise, it will be quite difficult to depend on someone else's signals.
You are absolutely right that anyone who wants to trade should try to learn themselves, understand market volatility and try different indicators. There may be small losses at the beginning but if you try to learn trading by yourself with small amount then there is no risk of much loss.
Profit and loss occur in every business, and always learn from your mistakes. People who always rely on other people's signals in trading never learn to trade. If signal givers can learn, why can't signal receivers learn?
