The problem for most traders is holding a position in the market once the trend is underway, and not to be bounced out in the inevitable round of pullnbacks and minor reversals which occur in all timeframes. No trend ever moves smoothly higher or lower without pausing and reversing against you and this is when emotion kicks in, and a decison is taken to close the position at a small profit. The problem then is one where a trader has several small lossess but few smaller profits and so the trading account fails to move forwards. To achieve this, profitable trends need to be maximised and this is where volume price analysis steps in to help and delivers a powerful tool in the trading armourry to help overcome this emotional response which can be so damaging.
