Hi guys,
I've installed the Backtesting Tool of XFFFF and it's GREAT, but i have some issues:

1) The backtesting itself works but not at 100%. Everytime in 1 run i execute 1 backtest (therefore i just run 1 backtest, on 1 pair, on 1 exchange, on 1 time window), i see the following errors. This doesn't appear if in 1 run i execute >1 backtests (e.g. when i vary the values of a parameter in the strategy from X to Y).

2) The second issue I'm facing regards the importing function that just doesn't work. The program get stuck during importing. The only thing i changed in the code is a pair of lines because i saw that the system was pointing towards the wrong folders (this is what i did --> https://github.com/xFFFFF/Gekko-BacktestTool/issues/45). Unfortunately this was not enough and i still get stuck.

3) And finally, the BT tool cannot generate a CSV file. It generates a file, but not a CSV. It generates like a blank file that put into Excel gives a very messy table that must be clean.

I'm pretty sure the installing went well, because the backtest itself works... but the rest just works bad or not at all.
Can please anyone help me??

Cheers!

I'm running gekko and it works great till now. But when I browsing gekko's code I found in the exchange/bitfinex.js (I'm dealing with that exchange) the getTrades is implemented as:
...
Trader.prototype.getTrades = function(since, callback, descending) {
......
if(since)
path += '?limit_trades=2000';
const handler = cb => this.bitfinex.trades(path, this.handleResponse('getTrades', cb));
retry(null, handler, processResponse);
......
}
...
It looks like value of "since" timestamp is skipped and it's just used to add a limit_trades=2000 to the API call. I tried to debug the code and that API call never returned entries more than 100.
I understand value of "since" is discarded because it's not supported by exchange, but what will happen if there's a flood of trades, say the trade rate reaches 1000/seconds. Given the getTrade API is call every 20 seconds by default, it looks like gekko will have a difficult time to generate correct candle in that case.

Could you guys please clarify if my speculation above is correct? It raises some concern about correctness of the trading bot .

I'm surprised I wasn't able to find anything on this topic, maybe I'm blind or it's so obvious that it's embarrassing to ask, either way it's the internet so here goes: 

I'm looking for Gekko to monitor the top 3 performers on Binance (highest 24 hour rise in price). If one of the coins meets my requirements (very simple requirements), Gekko will auto start my trading strategy for that coin, otherwise it will remain idle and continue to monitor. 

Is this possible? and if so could you point me in the right direction. I don't mind a challenge if it will be difficult to achieve. 

Thanks so much for your development. Gordon would be proud

Is there any possible way to transfer to and from a hardware wallet or a web wallet? I know having this information stored on a computer is bad but if it's cryptographically protected through the application I could see it working so long as nobody knew how to get ahold of the two-way cipher. Please let me know if this is at all feasible.

Thank you Mike for this excellent program.

Backtest tools for Gekko

CLI tools help to put together testing and optimizing strategies that extend the Gekko's Trading Bot capabilities – and thus you may get the most of it, and see what combinations were the best and the worst backed up by statistics.

The results appear in a CSV report file. It provides key statistics describing the overall performance of the selected strategies over the chosen historical timing of the simulation.

Hello,

since you can write your own API's for diffrent exchanges, I wondered if it would be possible to trade fiat currencys.

Would this be technicly possible? 
What is about trading with margin? Can Gekko do this?

Hi! 
Could you please tell me how I can add function Stop Loss into TSI strategy.
Thanks!

Hey people, happy to have jumped into Gekko after watching a few of Crypto49ers videos on Youtube. I was aware of Gekko over a year ago but only in the last few days have i jumped into the world of Gekko backtesting. 

After doing lots of reading & exploring, I want to say a massive big thank you to askmike & the other developers for sharing & developing a great thing! Im already looking forward to the new UI and watching closely at the exciting Gekkoplus project! 
So far i'm playing with cheap shit alt coins   so i'm happy to have a little punt at live trading here & there over the quiet xmas period... 

I initially installed on OSX and did some backtesting with some data, all went along fine but I did have some problems with npm & dependancies. They got solved easily with crypto49ers great videos and the info on here & the web. Then i used my Poloniex API key...  again all running fine on OSX. 

Then I installed on Pi  - so far only have run the --ui version. 
But i think my first mistake was using the same API key as my backtesting OSX - on my live Pi - i got fairly regular "nonce supplied" errors. A quick search on here and learn there is a 8 per second limit, so I generated a new API key, so one for live Pi & one for backtesting on mac. - But i'm still getting fairly regular nonce errors. on some occasions i get a whole html dump of a cloudflare page (504 error) in my terminal. 

So my 1st question: Are the nonce errors because my live bot is using 1 minute candles? Am i hammering the API too much? is there any easy solution?

2nd question: My pi is using 6gb card, my strat runner is pulling 1 min candles. Is this a ticking time-bomb?  my instinct tells me im going to run out of space in sqlite soon. Any ideas how much GB of disc space a month of 1 minute candles will be. Should i look at a cron script to clean up or is that a bad idea & required for the bot to work? 

3rd question: I sometimes get

Hello,

I tried to install "LSTM_MACD_RSI_V3" and got this error when I tried to run it:

 <-- POST /api/backtest
  xxx POST /api/backtest 500 226ms -

  Error: non-error thrown:
  This Gekko instance encountered an error and can't continue
      at Object.onerror (C:\Users\threi\Gekko\gekko-stable\node_modules\koa\lib\context.js:105:40)
      at <anonymous>
      at process._tickCallback (internal/process/next_tick.js:188:7)

I installed synaptic to my gekko folder and put the strategy file LSTM_MACD_RSI_V3.js in my strategy folder.
There is no .toml file. Is that the reason for the crash?

I'm very new to this and thankful for any help.

Regards,
Peter
