First of all, large and frequent losses are observed when trading using an unprofitable strategy. Therefore, it is important to first check its performance on a demo account and, if necessary, refine it there and improve it and only then switch to a real account. It is also important to trade with a reliable and regulated broker (for example, my broker is regulated by the FCA) with high-quality trading conditions, minimal spreads and commissions, instant execution and stable operation of trading platforms, which directly affects trading results and profitability.
