I think I can help here: I've found a "divergence indicator" for MetaTrader from Pavel Kulko. See here:

This may be a useful indicator. If you find something about this topic or even a MT source code, I'll try to make such indicator.

]]> Fri, 04 Mar 2011 07:37:24 +0000 https://forexsb.com/forum/post/8493/#p8493 <![CDATA[can a strategy deal with divergence / convergence]]> https://forexsb.com/forum/post/8492/#p8492 wondering if it is possible to deal with divergence/convergence when automating a strategy

for example when using the MACD, you may get successive entry signals, but not want to take an entry where the price has converged with the indicator, relative to the previous entry

I would actually like any advice on:

1.  whether this can be addressed with FSB, and
2. if not, could you point me in a direction where I might be able to research and find an answer

thanks in advance!!
