"Volume-Weighted MACD Histogram" is an indicator that shows how a volume-weighted moving average can be used to calculate moving average convergence/divergence (MACD). This technique was first used by Buff Dormeier, CMT, and has been written about since at least 2002. However, few traders use this idea in their trading.

Looking at the futures contract for the Standard & Poor's 500, we see that the VWMACD may be running out of steam. Of course, a single indicator should never be relied upon for a trading decision, but this one is flashing a cautionary signal.

The e-mini contract shows the same trend. See Figure 1.

The ten-year US Treasury contract (Figure 2) may also be showing that trouble lies ahead for stock market bulls. The VWMACD has turned bullish, which would mean higher interest rates. In general, traders assume higher interest rates are a negative for stocks.

The dollar contract is still in a bearish trend using the VWMACD, although it is nearing the zero line. A move above zero would be bullish for the dollar and potentially reverse the 31 weeks of negative readings of this indicator.

VWMACD offers potentially useful signals in futures markets and should be considered by traders looking for an edge in the markets. In particular, it is useful to look at a chart with MACD and note divergences. These may indicate that large traders are actively trading a contract.
