Specifically; I believe that the following code will do what you are 
looking for. For a good test, set from:/to: dates as Dec 11, 2007 and 
run your exploration across all stocks of NYSE, NASDAQ, AMEX. Using 
my data provider, I get 4129 rows. If you just want to try with a 
single symbol, use "A".

BackRef = 150;
VolumeSpike = (V>(MA(V,BackRef)+StDev(V,BackRef)));

LastSpikeBars = BarsSince(VolumeSpike);
LastSpikeVal = ValueWhen(VolumeSpike, Volume);

NextSpikeBars = ValueWhen(VolumeSpike, BarIndex(), 0) - BarIndex();
NextSpikeVal = ValueWhen(VolumeSpike, Volume, 0);

Filter = LastSpikeBars >= 0;
AddColumn(LastSpikeVal, "Last Spike");
AddColumn(LastSpikeBars, "Bars Ago", 4.0);
AddColumn(NextSpikeVal, "Next Spike");
AddColumn(NextSpikeBars, "Bars Later", 4.0);

_SECTION_BEGIN("Volume1");
Plot( Volume, _DEFAULT_NAME(), ParamColor("Color", colorBlueGrey ), 
ParamStyle( "Style", styleHistogram | styleOwnScale | styleThick, 
maskHistogram  ), 2 );
_SECTION_END();
