What deal lot size should I use on 50USD account with 1:20 leverage
With such a small account the only possibility is to learn scalping. But I warn you, scalping is the most difficult strategy of all. But also the one that teaches you the fastest of all.
1. You have to be prepared to lose it all many times over. I mean MANY TIMES before you learn.
2. Use 1/3 of your equity. I.E. a lot size of 333 USD. In this way you still can experiment with adding to it. Will you add to winners or to losers? HaHaHa ...
3. Alternatively, use 100% of your equity (= a lot of 1000 USD). You wil learn A LOT about yourself and your psychology.
WELCOME ABOARD, good progress and a lot of fun. It will not be fast.
PS. If you are serious about learning to scalp, observe waves. No Elliot waves, just common sense waves. Forget about trend, it has no meaning for scalping.
Observe wavelength and amplitude. It is all contained in there. Money management, timing, everything.
Forget about people talking about scalping as high frequency trading. This is BS and a direct path to lose.
Identify high probability situations and trade ONLY THOSE.
LOW FREQUENCY scalping is the way with a tiny account.
Hope this helps
