```My first response cut off the bottom of the volume lines rather than compressing the lines. Only change is calculation of adjustedVolume.

ClearAll[financialChart];

financialChart[company_String, startDate_List] :=

financialChart[company, startDate, Take[DateList[], 3]];

financialChart[company_String, startDate_List, endDate_List] :=

Module[
{dateForm, high, highest, closing, low, lowest,
volume, maxVolume, minVolume, adjustedVolume},

dateForm = {"MonthShort", "/", "DayShort", "/", "Year"};
high = FinancialData[company, "High", {startDate, endDate}];
highest = Max[high[[All, 2]]];
closing = FinancialData[company, {startDate, endDate}];
low = FinancialData[company, "Low", {startDate, endDate}];
lowest = Min[low[[All, 2]]];
volume = FinancialData[company, "Volume", {startDate, endDate}];
maxVolume = Max[volume[[All, 2]]];
minVolume = Min[volume[[All, 2]]];
adjustedVolume = {#[[1]], ((3*lowest - highest) +
(highest - lowest) #[[2]]/
maxVolume)/2} & /@ volume;

DateListPlot[{high, closing, low, adjustedVolume},
Filling -> {1 -> {{3}, Red},
4 -> {(3*lowest - highest)/2, {{Thick, Darker[Green, .6]}}}},
GridLines -> Automatic,
PlotMarkers -> {"", Style["-", {Bold, Black}], "", ""},
FrameLabel -> {None, "Price in Dollars (\$)"},
PlotLabel ->
FinancialData[company, "StandardName"] <> " (" <>

FinancialData[company, "Symbol"] <>
") Common Stock, " <>
DateString[startDate, dateForm] <>
" - " <>
DateString[endDate, dateForm],
ImageSize -> 500]];

financialChart["LLL", DatePlus[-90]]
