Yes indeed small deposit will difficult work using long term trading plan, but with small deposit we can trying use micro account or cent account which value 1$ is 100 cent on account and this still possible to working with money management, especially for retail trader start with small deposit still possibleI know from my own experience that it's extremely difficult and inconvenient to work with a small deposit. Firstly, it's really hard to follow money management, secondly, long-term trading with a small deposit is impossible.
i agree with you a small investment is always a wise idea in the initial days of trading.At initial level you must start your trading with small investment because at initial stage you don't know about the ups and downs of the market. There are mostly higher chances to lose the money.If you make a small investment than you can bear the small loss because at initial level you didn't afford the greater loss.
