High Volume Node. An area on the market profileA way of reading the market that recognizes either time spent or volume traded at a particular price level. A market profile can be either made up of “TPO’s” (time price opportunities), or volume. TPO’s measure how much time was spent at a particular price, while volume-based market profiles measure how much volume traded at a particular price. Generally, market profile is used in the trading of futures, especially the /ES. ShadowTrader utilizes volume based profiles. that would look very wide on a composite profileA market profile chart that aggregates all of the volume of all of its distribution along the Y axis, forming peaks and valleys in areas of high and low volume. that has volume histograms on it’s Y axis. In general, markets are pulled towards high volume nodes and reject away from low volume nodes. This is why the bottoms and topsTops refers to the highest or lowest possible price that will be accepted to enter a trade when bidding or offering using limit orders. Therefore if the moderator says “Shorting IBM at 84.60, 84.50 tops”, it means that limit orders between 84.60 and 84.50 are being used to enter the position. of single printsAny section of the market profile distribution that is only one TPO wide. Single prints are a sign of emotional buying or selling as very little time was spent at those levels and thus there is no value there. The endpoints of single print sections are considered to be potential support or resistance points. or spikes are usually supportive or resistant.
