discipline not only a human habit it also a character , to be experienced in discipline we have to be mentally strong first of all, otherwise no way to maintain

Some 'beginners-tips' from me:
- start with a demo account, learn the best strategy for your own mindset (everyone is different) in more than 6 months. after that try with a low budget first (even if you could afford more)
- always use low leverages (if trading outside of MetaTrader)
- always use microlots first (depending on your account (your max. account leverage) and asset leverages (assets need to be tested))
- patience, a lot of patience! if you trade the 'professional way' with sl and tp, always respect them and also the charts. if you trade the 'semi-professional' or 'hedged way' use microlots or low leverages only combined with loads more of patience and professional charts analytics (best without any indicators) on higher time frames (D1, W1)
- never let your margin-level come to less than 1000% (if you trade with 0,01lot; with higher lot-sizes you might need to use an even higher min. margin-level), if it's lower it's gambling (you won't have any chance in a flashcrash scenario)
- never be a greedy person (also outside of trading); make some trading plans (maybe start a private trading journal with goals like 100, 50 or 30% per month, if not reached set them lower)
- use only 1 of your favorite indicators (and learn how it could work in your favor)

Examples:
- MetaTrader account with 1:500 leverage: always start with 0,01lot if your account is lower than 2k, use 0,02lot if the account is lower than 3k, and so on (only try with 1lot (or higher) if the account is higher than 100k)
- with non-MT accounts: if in the EU use the ESMA's max. leverages, if outside: use the same max. leverage as with an ESMA account (e.g. 1:30 for currencies, 1:10 for oil, 1:2 for cryptos and stocks, and so on)

experience traders dont depend on same trading strategies completely, they change their strategy according to market movements.

in Fx leverage is a very complicated issue , sometimes it bring profit very rapidly , sometimes it causes a great losses and risk in spite of having risk management , but after all its one of the major financial issue in Forex.
