Would be nice to have in MT5 subminute TFs. I understand it is a lot of data to be downloaded from data servers but it could be somehow limited for just a couple of days of such fine resolution data. Other platforms allow even tick data or consolidated ticks. 5s data would be good.

I'm looking for an Ord Volume indicator for MT4 that will work on any timeframe. Anyone know where I can find one or if not, anyone willing to code it for me? It is described in a pdf document you can download off the web called "The Secret Science of Price and Volume" by Timothy Ord starting on...
I've seen a lot of posts about if it is possible to protect your ea from decompiling back to source code. Technically, it seems impossible. However, I think there is a strategy that will make it immensely difficult from a pure programming perspective. Its just applying Sun Tzu's ancient maxim...
