No, it is not possible.

@pixelephant said in Zigzag Indicator:

is looking backwards

How do you identify swings without looking backwards? Because the only known method of identifying a swing is when it has already happened.

Again, you may want to read the Docs - Quickstart Guide

That sounds almost like sacrilege. Who would dare doing such a thing ...

Fo sure not those who dare reading the Docs - Quickstart Guide

your thoughts please

Run a speed test and use the syntax which better suits you.

The IB store/broker concept was developed for a single account concept.

I made a simple moving average crossover stratergy to buy and sell AAPL stocks

Sorry, but you haven't.

@backtrader14 said in How to execute a buy sell order in backtrader?:

class MyStrategy(bt.Strategy):
    def __init__(self):
        self.sma= bt.ind.SMA(period=5)

If you only have 1 moving average, it is difficult to conceive that you have a moving average crossover strategy.

You will argue ... "it's a crossover nevertheless ... i was righ". No, you are not. Precision is important: you want to play with money at some point int time.

But the TradeAnalyzer result shows that only two trades

Change to a moving average crossover.

@backtrader14 said in How to execute a buy sell order in backtrader?:

    def next(self):
        if self.sma[0]>self.data.close[0]:
        # current sma greater than current close price
            print('BUY CREATE, %.2f' % self.data.close[0])
            self.buy()
        elif self.sma[0]<self.data.close[0]:
        # current sma lesser than current close price
            print('SELL CREATE, %.2f' % self.data.close[0])
            self.sell()

You are not even reversing the position, you are at some point in time opening a position and simply closing it at some other point in time. You have print statements but your log is that of the TradeAnalyzer which can only tell you what has happened and not why.

Do the following:

• Decide if you want a moving average crossover or another type of crossover.
• Learn about the close method to close an open position or reverse the position using the appropriate size
• You may want to check the position size
• Use notify_order and log what the notifications tell you.

Individual operations (i.e.: dynamic lines created through operations) are NOT indicators and only indicators do plot.

You should properly wrap things in the proper structure if you want them plotted. See Docs - Plotting

Yes, you close blindly when entering the market.

@backtrader14 said in How to feed a custom pandas dataframe in backtrader?:

class PandasData(bt.feed.PandasData):
    linesoverride = True  # discard usual OHLC structure
    # datetime must be present and last

In this case it is quite unclear why you would want to discard the OHLC structure when you apparently have one. This is for sure not code copied from anywhere. And it won't probably work. You have also copied the comment that says that "datetime must present and last", but don't define a datetime line.

I am rather sure that you are not looking to override the preexisting datetime-OHLC-volume structure (i.e.: the predefined lines)

See: https://community.backtrader.com/topic/1832/creating-bid-ask-pandas-datafeed-error

And see: Docs - Extending a Data Feed

@backtrader14 said in How to feed a custom pandas dataframe in backtrader?:

I understand params is method's parameters but lines I have never come across this concept in programming

It's not a programming concept. It's a trading concept. You get all the close prices, plot them along the date axis and join them with a line ... and you have a line. The same you have with any other component of a time series. Call it array if that makes your life easier.

See:

• Docs - Platform Concepts

@backtrader14 said in How to feed a custom pandas dataframe in backtrader?:

df = bt.feeds.PandasData(dataname=data)
#df=PandasData(dataname=data)
cerebro.adddata(df)

Furthermore if you define a custom class and you don't use it ... because you use the internal data feed.

It will for sure never find your pct field.

Taking into account that you know the order in which your columns are in the dataframe, it seems rather strange to redefine the parameters and set all of them to -1. The only reason to redefine the parameters would be to assign fixed values to them, to make sure you are locating the columns.
