Never risk more than 2% of your money in 1 trade.
One of the most important aspect of forex trading is money management.
I open 3 lots/3 Mini lots per trade.
Always have a stoploss for everytrade.
If I risk x pips on a trade my take profit 1 will be x pips.
When take profit 1 is hit one lot is closed and and move the stoploss on the other two lots to breakeven. This way we have locked in profits on the trade.
