Thanks for complement. I'll consider to add JS as on option. As regards releasing server side code to open source, right now i do not have plans to do this, though may change mind in the future. By the way, some client code is available at Github https://github.com/pulsecat/cryptrade the repository includes core library on which Cryptotrader based + tool for automated trading in standalone manner.

It is a good point. Actually, every Instrument object has 'fee' property, though it is not documented yet.
Example:

Is something broken with talib.MFI? I keep getting NaNs for some reason.

Also, what happened to the automatic data update feature it had before? You used to just change the dates and periods, and whatever, and hit Backtest. Now you have to hit refresh, losing your buy/sell markers on the data, then get prompted with a window containing information you already know.

Seems the problem is that 'volume' array's length is 1, all others are preloaded with 100. They all have to be the same length:

Agreed. This is annoying usability issue.


If you notice this problem again, please pm to me link to backtest session.


volumes - array of volume values, volume - is a current volume

OK, pulsecat, but it would be nice if the log record limit would be synchronized with the limit we hit on green refresh button right to "start at end at" fields. If the refresh button gives us candle data this data should also fit in log IMHO. Thanks for looking into this issue.

I am looking for that, too. Someone solved it already?

Thank you very much. I´ll give it a try.

I am trying to do something similar and build on a simple script.
However no matter what I do I can not keep the instrument.price stored.


#Simple buy and sell over price with EMA
init: (context)->
    context.buy_price = 0

handle: (context, data)->
    instrument = data.instruments[0]
    short = instrument.ema(9)
    long = instrument.ema(19)
    plot
        short: short
        long: long
    if short > long
        buy instrument #works up to here
        context.buy_price = instrument.price #The sell fails by not selling the instrument over the (purchased) price
    else if  context.buy_price > (instrument.price*1.01)
        orderId = sell instrument

I assume it has to do with the iff statements, because I can get the sell to work but then the buy just buys as soon as the script starts.
Thanks for any ideas and help.
