-- Warning - Danger! --
Low leverage is mandatory unless you don't mind
wiping out your account before breakfast. Forex
brokers always push high leverage because they
profit when you lose. Low leverage not only
limits your risk but also any gains. So people
that do this activity follow their broker's advice
and use high leverage (with their small accounts)
and get wiped out like clockwork.
Without placing a single trade, just having
an account with a Forex broker is a risk.
Also, brokers can't guarantee your stops,
so practically speaking your entire account
is always at risk. Brokers are not banks.
Also, the world's largest banks are now
leveraged more than ever...
worse than during the crash of 2008.
Instead, grow a vegetable garden, something
that you will benefit from enormously. What
an education it was to learn about all this...
Low Leverage,
Low Frequency:
- Designed Forex Trade Visualization Lab in PHP with risk analysis graphs (GD), price charts, optionally showing open and closed trades, and multiple simulations
- Developed algorithms for low leverage, low frequency trading based on fundamental analysis, then wrote live trading programs that implemented them
- Wrote many indicators and trading expert advisors (EAs) in MQL4 for Metatrader 4
