Here are some questions or new features

• how to implement trailing stop tool? it'd be great if can share more info?

• what's thoughts for polling orders from exchange every second? how about using user data stream?

• in strategy, currently Timeframe is a single frame, how about i will use both 15m and 1h for one asset for example? and if so, maybe need to resample the candles?

• how about adding hooks in strategy, for scenarios: when putting order, i'd like to refer to outside sources, etc.

• any thoughts about integrating with 3rd frontend tool? like tradingview, or open source tools, etc?

Hi @davidxiao

how to implement trailing stop tool? it'd be great if can share more info?

I will include a new feature soon, strategies will have access to partial candles, with this feature will be easy to create this tool.

what's thoughts for polling orders from exchange every second? how about using user data stream?

The pooling is very optimized, we fetch data only when the bot have NEW, PENDING, and PARTIAL FILLED orders in the storage. But we can include this feature, but it is not a priority for now.

in strategy, currently Timeframe is a single frame, how about i will use both 15m and 1h for one asset for example? and if so, maybe need to resample the candles?

Its very complex to provide multiple timeframes for a given strategy, you can use a small timeframe and resample it in the Indicator function to create new samples. I wonder to keep the strategy interface simplest as possible.

how about adding hooks in strategy, for scenarios: when putting order, i'd like to refer to outside sources, etc.

You can use OrderFeeds and subscribe it in the ninjabot Run(), with the option, ninjabot.WithOrderSubscription. Any struct that implements the bellow interface is valid to receive orders updates. It's the same for candles (WithCandleSubscription). Chart module uses this approach.

type OrderSubscriber interface {
	OnOrder(model.Order)
}

any thoughts about integrating with 3rd frontend tool? like tradingview, or open source tools, etc?

I will try to create an isolated frontend with more features, such as custom indicatos, real-time charts, but it is in the roadmap. You can subscribe for update here: #124

how about using user data stream?
