I have expertise in stock trading models which uses data from various time frames and create strategies for equities mainly. Was unable to see your email on your profile page. How to reach out?

@ssb @backtrader Can you answer this pls?

@han-shen

I would expect that you would have to pass the period,stdperiod values when in instantiate the class.

@kk7134 according to the code of this indicator, it automatically get the high, low, close of the data you pass to it. Have you tried something like :
self.fib = bt.indicators.FibonacciPivotPoint(self.data1, _autoplot=False)

then print :
self.fib.lines.p[0]
self.lines.s1[0]
etc.

?

@wymak The problem is with the declaration: cs = simpleStrategy. You don't actually create a simpleStrategy object you simply assign the object type to the variable, so when you can't call cs.retrieveLog() at the end.

The object is actually created by cerebro.run() and I don't know if there is a way to get to it from outside. A potential solution is for you to pass the log function as an argument to your strategy and then use that to log. The function can then be declared from somewhere you can get to the buffer.

@jin-lin Did you ever figure this out? I have the same problem, I'm wondering if something changed with IBTWS that breaks the IbPy package or something like that.

I just checked and the SMMA has the following attributes:

['IndType', 'ObsType', 'PriceClose', 'PriceDateTime', 'PriceHigh', 'PriceLow', 'PriceOpen', 'PriceOpenInteres', 'PriceVolume', 'StratType', '_OwnerCls', '__abs__', '__add__', '__bool__', '__call__', '__class__', '__delattr__', '__dict__', '__dir__', '__div__', '__doc__', '__eq__', '__floordiv__', '__format__', '__ge__', '__getattr__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__len__', '__lt__', '__module__', '__mul__', '__ne__', '__neg__', '__new__', '__nonzero__', '__pow__', '__radd__', '__rdiv__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__', '__rmul__', '__rpow__', '__rsub__', '__rtruediv__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', '__truediv__', '__weakref__', '_addnotification', '_clk_update', '_clock', '_getline', '_lineiterators', '_ltype', '_makeoperation', '_makeoperationown', '_mindatas', '_minperiod', '_next', '_nextforce', '_notify', '_once', '_operation', '_operation_stage1', '_operation_stage2', '_operationown', '_operationown_stage1', '_operationown_stage2', '_opstage', '_owner', '_periodrecalc', '_plotinit', '_plotlabel', '_roperation', '_stage1', '_stage2', 'addindicator', 'addminperiod', 'advance', 'alias', 'aliased', 'array', 'backwards', 'bind2line', 'bind2lines', 'bindlines', 'csv', 'data', 'data0', 'data0_0', 'data_0', 'datas', 'ddatas', 'dnames', 'extend', 'forward', 'frompackages', 'getindicators', 'getindicators_lines', 'getobservers', 'home', 'incminperiod', 'l', 'line', 'line0', 'line_0', 'linealias', 'lines', 'minbuffer', 'next', 'nextstart', 'once', 'once_via_next', 'oncestart', 'oncestart_via_nextstart', 'p', 'packages', 'params', 'plotinfo', 'plotlabel', 'plotlines', 'prenext', 'preonce', 'preonce_via_prenext', 'qbuffer', 'reset', 'rewind', 'setminperiod', 'updateminperiod']

How can i give it a 'high' attribute?

@李杰 Hey, I know it's an old topic but did you manage to solve it? I have the same issue

Okay, so I figured out getting the name part as well. Instead of using iterator directly, we can get a tuple of lines defined inside the indicator with _getlines() method. Then we can loop over that tuple and each time call _getline() method with line name to return the actual lines object from which we can get the data sample.

Example code:

for ind in self._owner.getindicators(): line_names=ind._getlines() ind_name=type(ind).__name__ for line_name in line_names: line=ind._getline(line_name) print("Indicator "+ind_name+" line "+str(line_name)+" value is "+str(line[0]))

Still working on the other issue with LinePlotterIndicator() method as mentioned above so if anybody can help then that would be greatly appreciated!

@pierre-cilliers-0 Thanks for your answer and the code.
I wrote a cancel method which parse all existing orders and close active ones, but yours is more precise and smarter.
