i used to make good money then over 3-4 trades lose it all......
i think it is because i did not have a clue, like most people, what was a channel, leave alone how to trade it, if at all.
i realise now that either to go one side, meaning in a bull channel, only buy....and then have a lot of patience as the market crawls up or, as i usually prefer, wait for a better pattern even if means waiting 2-3 hours.
i am now not losing widly for no apparent reason.
learning to recognise tight channel has hugely helped my profitability and mental frame of mind and kept me focusing on making trades solely on basis of technicals, rather than reacting to whipsaws, or on feel or guessing.
