Several readers stimulate got asked for explanations of the Market Delta charts that I postal service during the week. Details nearly the "footprint charts" tin live on constitute on the Market Delta site, only this postal service should convey newcomers upwards to speed.
If you lot click on the nautical chart above, you'll come across that we're looking at 60-minute bars from the preopening merchandise of 9/18/09. I've blown upwards a segment of the nautical chart for easier viewing too annotation.
Within the bars, you'll come across 2 numbers. The outset is the pose out of contracts traded at that fourth dimension too toll when that toll was the marketplace bid price. The 2nd is the pose out of contracts traded at that fourth dimension too toll when the toll was the marketplace offering price. When the book at the offering exceeds that at the bid, the colouring within the bar is coded green. That shows that buyers are to a greater extent than aggressive on average: willing to pay upwards for the offering price. When the book at the bid exceeds that at the offer, the colouring within the bar is coded red. That indicates that sellers are to a greater extent than aggressive: willing to select the lower, bid toll to become out of the market.
We tin await at shifts from dark-green to cerise (and vice versa) both within bars (to demonstrate buyers or sellers becoming to a greater extent than or less aggressive equally nosotros movement upwards or downwards too to come across if total volume--the total traded at bid too offer--is expanding equally nosotros move) too across bars (to demonstrate if buying or selling pressure level is waning or heightening over time).
The cerise trouble on the nautical chart represents the market's volume-weighted average toll (VWAP), which is the average toll traded since that day's session began, weighted yesteryear the book of transactions at each price. VWAP hence is to a greater extent than affected yesteryear trading during regular trading hours (when book is highest) than during overnight hours. During tendency days, nosotros rest consistently to a higher house or below VWAP; during gain days, nosotros tend to oscillate unopen to VWAP. False breakout moves volition contrary toward VWAP; sustained breakouts volition turn down VWAP on company book too non provide to that average price.
The histogram at the bottom of the nautical chart sums the book transacted at the offering minus the book transacted at the bid for each bar menses (in this case, lx minutes). If to a greater extent than book is transacted at the offer, that departure is coded inwards dark-green too is displayed to a higher house the horizontal axis. If to a greater extent than book is transacted at the bid for that bar period, the departure is coded inwards cerise too is displayed below the horizontal axis. Seeing how nosotros shift buying too selling stance from bar to bar gives helpful clues equally to whether buying or selling pressure level is waning or strengthening over time.
Finally, the histogram at the correct of the nautical chart displays the total book transacted at each marketplace price. This gives us a distribution display like to Market Profile. From that display, nosotros tin come across where the bulk of book has been transacted. That surface area represents the market's guess of value; weak book moves to a higher house or below that surface area volition tend to autumn dorsum into the value range, piece expanded book to a higher house or below the surface area suggests breakout moves too credence of value higher or lower. The book bulges at diverse prices tin live on conceptualized equally near-term resistance too support; the cast of the total distribution tin offering helpful clues equally to the marketplace construction on the solar daytime timeframe: whether we're edifice a tendency day, gain day, double distribution day, etc.
If you lot review my posts that characteristic the Market Delta charts, you'll selection upwards on patterns that are useful for short-term traders. I volition live on adding to those posts inwards coming days too weeks.
