Basic OsMA expert advisor

[Deleted] 2008.02.15 20:19

Hello,

I have been searching everywhere for a basic expert advisor for MT4 that does the following:

Goes long when OsMA goes above 0 and short when goes below 0.

If anyone has this, or knows where to find it, please let me know.
Thanks.

The MACD sample EA does this in effect, as it trades the general method you describe.

OsMA is an alternative visual representation of MACD - and also a bit simpler to code!

I use OsMA alot - but the EA code below is not mine, but will show its use. You could strip out all the code bar what you want - but a 'one liner' EA will lose money in real trading - even though it might be profitable on back-testing (on Metaquotes history data).

NB - in most time frames less than a day, just going +/- zero will flick you in & out of positions during periods of low volatility & lose money.

Check how the MACD sample EA handles its threshold.

Also add a trend indicator before getting into a trade (perhaps ADX>30) as MACD/OsMA is a trend follower and will lose its way during ranging conditions.

Also useful is a volatility indicator to make sure there will be follow through? Perhaps StDev?

Good Luck
