I've been using Etrade Pro for about 4 months. On my daily charts, I stripped out the MACD Line and the MACD Signal line and just have the MACD Historgram. When I did this, I noticed that the MACD Histogram was out of sync with market data. On Etrade Pro, the MACD Histogram lags every other charting service, Stockcharts, Big Charts, etc., by at least one day.
By this I mean that if you look at the MACD Histogram by itself, the reading you get today may be the reading that you should have gotten yesterday or the day before. Regardless, the MACD Histogram on Etrade Pro is giving false signals, and that could cost you money.
I have contacted Etrade and their Technical Support. They have acknowledged the problem but told me they would not fix it. This is unacceptable.
If you have Etrade Pro, check this out for yourself. If you haven't messed with your MACD settings then they should be the default settings which are 12,26,9, the industry standard. Etrade uses a different formula but if you haven't played with your MACD settings then they should be the default.
If you find the above to be true in your Etrade Pro trading platform, would you please contact Etrade and let them know you want this fixed. I have done this but I'm only one person and they couldn't care less about me. If they were to start getting complaints from several different Etrade Pro users then they would have to do something.
