Search results for "MACD EA" and "MACD robot" have shown up in the website statistics lately. While I coded some MACD EA's in the past, none of them were very successful.
Out of interest, I attempted to code another MACD robot last night using all the coding techniques I've learned over the last 3 years, but to no avail - MACD doesn't appear to lend itself to successful automated trading.
Even using it just to determine trend on higher time frames and using other methods for trade entries were failures.
While it's always possible someone has coded a successful MACD based EA, or while it may be useful for trading manually, it's not something I've ever had any luck with.
