click file, new bar chart, then type in the formular, select 1m , select histogram type at where you select candle or bar type.
In tradestation I'm able to hold the extreme values of each bar in a variable and plot them as separate lines on the chart. In the attached pic the thin portion of each bar represents the extremes and the thick portion represents the last value, which fluctuates with each tick. Also look at Spooztrader's charts. He shows the same info in a slightly different way.
Thanks, NKHOI, for the information, I've tried for several days about: file, newbar chart and typed in the formular, select 1-minute, select histogram and message came out each time with"not available". This computer, I use now, runs window-VISTA. Hmmm, not sure what to do now.
Qcharts has Vista issues. See here: http://www.elitetrader.com/vb/showthread.php?s=&postid=1400925&highlight=vista#post1400925
txuk, When you plot the extreme values, which ones do you use? For example, if the Str/Squ formula = (YM-INDU) - offset, do you use the (High YM - High INDU) - offset for one set of plot values and the (Low YM - Low INDU) - offset for another set of plot values? I am collecting the tick data for the YM and the INDU in Excel and within each 1-minute bar, I have extreme values (highs and lows). I'm not sure which ones to be using in my formula to create my histogram. From my latest observations, there seems to be enough variance in the extremes (highs and lows) even within a 1-minute bar (even more so in longer bar fractals), that this could affect the conclusions one might draw from their histogram. Thanks for any light you could shed on this for me.
WG, you can ignore the High/Low values of YM and INDU. You want to always work with the immediate spread of YM minus INDU minus Offset. At the beginning of each 1min bar, reset your sq/str extreme variables. With each passing tick re-calc the spread. If the spread is at its highest or lowest point on this bar, then update your extreme values. So you are plotting three values on each bar: current spread, hi extreme, lo extreme. Hope this helps
