There is an indicator called 'fve" or finite volume elements that I was checking out a few months ago. It is coded for eSignal already. Here is an excerp from the article (and the link)

"The finite volume elements (FVE) indicator is yet another money flow indicator â but it takes into account both intra- and interday price action.
Most technical analysts underestimate volume indicators in favor of pricebased indicators or price pattern recognition. Volume often leads price, and volume indicators can predict this price change by observing the delicate balance of supply and demand in the never-ending battle between buyers and sellers, bulls and bears. To help analyze crowd psychology and profit from subsequent price moves, I created the finite volume elements (FVE) indicator.
VOLUME-BASED INDICATORS
Money flow, accumulation/distribution, and balance of power are all terms synonymous with volumebased indicators. I have been using volume indicators for some time as my prime tools in making trading decisions, and Iâve found that divergences between volume and price are often the only clues to important reversals. Volume indicators use intraday (the relation of the close to the midpoint of the day) or interday (todayâs price relative to yesterdayâs) price action to calculate whether money is flowing in or out of a security. The best-known intraday money flow indicators include Marc Chaikinâs money flow index (CMF), David Bostianâs intraday intensity, and Williamsâ accumulation/ distribution. These all ignore the stockâs price change relative to the past, but calculate accumulation or distribution according to the relation between the closing price and the midpoint (Chaikin and Bostian) or the open (Williams) of the day.
On the other hand, the best-known money flow indicators that use interday price changes are onbalance volume (OBV), David Marksteinâs volumeprice trend, and the money flow index (MFI), which is a volume-weighted relative strength index (RSI)."
