Demorelease 2.13.10 / API 2.7.38

If you have multiple Fiboretracement Objects or ILeveledChartObjects, the levels are not attached to the Object and the Levellabels are not attached to the levels.

i.e.

FiboRetracement 1 has 5 Levels
FiboRetracement 2 has 10 Levels

Problem 1: getLevelsCount will provide for each FiboRetracement 15 Levels.
Problem 2: The Label in addLevel or setLevelLabel is related to the Levelvalue (i.e. 50 %) not to the Level (i.e. Level 10). getLevelLabel provide correct Labels for each level, but the chart shows the Labels related to the values (i.e. all 50 % levels show the same label).

Maybe this will help your debugging: If you try to set a levellabel for a level that does not exist, the error-message shows an array of two values where the first value is always 0. I guess the first value should be related to the FiboRectracement Object and is not linked.

A solution would be very appreciated.

Thank you in advance and best regards

A little extension: Define a FiboRetracement Object A with 5 Levels and a FiboRetracement Object B with 10 Levels. As soon as B is created, A will be extended to 10 Levels.

A solution would be welcome.

Thank you in advance and best regards

Problem 1: Is not reproducible, please, provide your strategy code to find out what's the problem.
Problem 2: and.... where is the problem actually?

About "debugging" - this error message appears due to you try to work with not existed level. There will be no problem if you specify correct indexes.

Ok - here is a code to test that produce exactly the results as described in the first posting. There is no difference between Fiboobject1 and FiboObject2.
