Trading is all about how you handle your trades. Very little to do TA. Technical Analysis is just a smart way of loosing money..with lot of confidence.
Its like, when someone throws 4 heads in a row and is about to toss the coin for the 5th time, you feel confident that tails will be outcome, since 5 heads in a row is technically a very low probability event. Fact is, probability of tails is still 50-50.
No matter how strong the signal, acknowledging that every trade has equal chance of hitting stop loss is the first key to success. Respect the risk and keep the damage any trade can do (if it hits the SL) under tolerable limits.
What we see on the charts is basically what the eyes want to see. If you are holding puts and things are not going as you hoped, you will find technical reasons to hold on to the trade. You will find other analyst who will support your decision and that will give you extra confidence to loose more money.
Fact is, TA is just a tool we use to time our entry in the direction of our bias. How we handle the trade is a product of our experience as a trader. A good trader knows when to give room to a trade, when to trail it aggressively or when to book out at fixed targets. He knows when a trade has lost its edge and is looking to get out with minimum damage.
