Hello muradsaleh

Sorry for delay, have missed your post.
Well, the same TA indicators and methods are used but fundamental reasons should be taken into account.
For position trading your are looking at daily - weekly (and monthly) charts, for swing - on 4H, daily.
Leverages should be small (max 1:10 for swing, max 1:4 for position). Even without leverage performance above 20% annually may be achieved.
This are the more conservative (less risky) and stable approach to the forex investing. Therefore big money may be involved.
