The 45 degree line is an interesting 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. nuance. It occurs when a 45 degree line can be drawn from the lowest point of a distribution to its widest point (TPO(MP) Stands for “Time Price Opportunity”. It is the smallest unit of measure displayed any market profile graphic, denoted by a single letter. Each TPO represents a point of time where the market being charted trades at a specific price. A single TPO is printed on the chart every time that a certain price is touched during any time period. Typically, the periods are set to 30 minutes. Therefore, every different letter that you see in the market profile distribution denotes a different 30 minute period. POCPoint of Control, also known as the "fairest price to do business". It is the price level in the /ES where the greatest amount of volume in the prior RTH session traded. ShadowTrader measures the POC using volume but the traditional way is to mark off the widest point of the day's distribution where the most TPO's printed going across from left to right, indicating that that was the price where the most time was spent. It's important to pay attention to both the volume POC and the TPO POC.). This is a sign that sellers have painted themselves into a corner near the lows of the session and creates potential for an upward reversal in the next session. As less and less time is spent the closer you get to the low of the session, sellers are essentially initiating shorts at less and less value. 45 degree line lows should be assumed to be secure until they are breached. The pattern is generally only noted in RTHRegular Trading Hours. In the /ES this means the price action from 9:30am EST to 4:15pm EST only. sessions but they have shown to be relatively reliable signals in overnight sessions as well.
The obvious question is always whether or not the 45 degree line can be drawn in from the high of the day to the POCPoint of Control, also known as the "fairest price to do business". It is the price level in the /ES where the greatest amount of volume in the prior RTH session traded. ShadowTrader measures the POC using volume but the traditional way is to mark off the widest point of the day's distribution where the most TPO's printed going across from left to right, indicating that that was the price where the most time was spent. It's important to pay attention to both the volume POC and the TPO POC.. Our experience has shown that it is not nearly as powerful of a signal. This is probably due to the fact that short selling is most often a tool of the shorter term trader and longs entering with what seems to be poor location may have longer timeframe outlook.
