2/ Exposure is the key, not the individual trades. --> still having issue with this. The current approach is to almost always close a trade with a gain (balance gain).
3/ One bar of 1M or 5M doesn't change direction of the move (trend). Better to look at the 5M chart before enter.
4/ When "near the MC" or "running out of margin", the "add more" is not a good strategy. Need to trade the opposite, that leads to reducing the exposure that actually is in the losing side.
5/ News that need not miss:
EIA Crude Oil Stocks Change (75 pip move for oil: 60.41 move up to 61.16 on Dec 18,2019 at 10:00AM Dallas time). Happen weekly.
6/ "Headache, pimples on the head, coldness on the head & ears" is the result of staying up (or wake up while sleeping) late at night staring at the laptop. This hurts the health and the trade performance too.
