When the market profile begins to build out or develop in a certain area, it is said that the market is accepting those prices. This can be measured either in time spent or amount of volume that is transacted. It is generally understood that ShadowTrader defines acceptance as more of a time dynamic than a volume one. A good rule of thumb is to look for at least two TPO periods to print in the accepted area. The acceptance confirms that a significant amount of market participants are transacting at those levels.
