Hello manueldecastro,

Thanks for your reply.

Yes, you can export the swing points using the streamwriter. The swing indicator is different as you noted.

The swing indicator does not "confirm" a swing point until the strength number of bars has passed the swing point. The default strength setting is 5 so on the 5th bar after the prospective swing point the swing is confirmed and then the dots are first drawn back to the swing point and then are drawn forward at the same level for each new bar until a new swing is found.

If you print out every current bar value of swing and then look at the list of values, you can see where the swing changes, and if you need to know when or what bar the swing starts from it would be on the 5th bar before the change in the data. (assuming strength of 5).

Hello manueldecastro,

Thanks for your reply.

Yes, you could use an array to hold the last N values.
