Share New Research 
Hi All!
We're excited to share that coming soon there will be L1 quote data automatically included in backtests for US equity stocks. We are also updating the historical and live data feed to be based on the SIP; the aggregated tick feed from all the exchanges.
We strive to make our backtests as close as possible to live trading, but this modeling is difficult without the full volume and a realistic spread. With the new data sources, it should be a significant advance in the realism of the backtests. The new source would be identical to paper trading, allowing your live paper trading to be more realistic than ever.
If you are interested in the engineering please feel free to subscribe to follow along. Once the code is ready and data in place we'll merge the pull-request and hot-swap the data over. There should be no downtime. I will also comment on this discussion thread once the merge is complete.
Important Note #1: Because the backtests will now have spread; your backtest performance will likely be worse than it was before! I understand this will be upsetting but please see it as a more realistic reflection of the model. It means if you buy and sell in the same second, it will constantly lose the spread between the equity bid and ask. This cost will be significant if you are trading quickly or on low liquidity assets.
Important Note #2: Quote data is approximately 3x the amount of data. Although the processing speed of LEAN will get faster in "data points per second" -- the absolute wall-clock time for the backtest will increase. We've got 2-3 massive engineering leaps up our sleeves which should offset that delay by running 300% faster... there will be 1-2 weeks where the backtest will be slower while we install those new engineering advances.
We expect this upgrade to happen in the next week. Thank you for supporting QuantConnect! Here's to an awesome 2020!
Best Regards,
Jared

Hey Dave, we have finished the code changes required to maintain backward compatibility but didn't want to deploy it on the weekend. We've now got the data, code, and new tests in place and will re-deploy Monday-AM.

Sorry Dave still delayed; please subscribe to notifications and I'll update this thread as soon as its pushed. We found differences in the ticker symbology and are mapping the tickers back to the current QC format so the data should be nearly identical and not require changes to your code.
It'll likely be 1 day of engineering, 2 days of data processing and then 1 day of retesting. ETA Thursday-Friday.

Grigori Gustin
Hi Jared/QC team,
I have noticed that there is access to ask/bid prices in research notebooks for second resolution.
However, I could not access to tick data - is there any work still in progress or the problem is in my code?
Also, is ask/bid data is already available during backtesting?
Thanks, Grigori.

Hey Grigori! Yes, it was deployed quietly yesterday.
Tick data is also available but it is not the same format as QuoteBars, each Tick has a TickType attached to it. The value of TickType.Quote marks ticks which are bids/asks. These are presented as a list for a specific moment of time.
Our tick data for Equities is now also timestamped to the millisecond! Previously it was rounded down to the previous second
--.
Live Trading does not have the new quote feed yet -- we're working on that and it'll be installed in the next week or two. We're literally waiting on physical delivery of some 10GB fiber modules and with the virus, everything is moving slowly.

Trying to access Resolution.Tick through qb.History() call gives me the following exception:
"Exception : cannot handle a non-unique multi-index!"
Still did not figure out the root cause, the date range seems valid (couple of hours) and it worked before.
Could you please help me on this?

Thanks Hugh;
All going well - we'll do the installation of the new live feed this weekend. We've wired up a brand new rack and are just waiting on a cross-connect cable install for the new data feed. Old live algorithms will need to be stopped and redeployed to move to the new infrastructure.

Laurent Crouzet
Jared Broad I really think it will be an important and a very useful development for QC and the QC's community that all algorithms (those that are working and the new ones) use the new bid/ask structure!
If I understand well, that would also imply that all currently validated Alphas (those on the marketplace) will be stopped and redeployed, right?
Does it also mean that it would deplete the portfolio (cancellation of all insights) of these Alphas? Or as long as everything goes smoothly during the week-end (as no market is open), the Alphas will still keep their current investments?

Laurent: All QuantConnect backtest algorithms currently use spread, and soon live trading will as well. Once the new live feed is installed Alphas will need to be stopped and redeployed. An Alpha should reinitialize its state in the event of a shutdown, so it should resume their previous positions. When we eventually restart them we'll do it after market close; before universe selection; on Friday. This should minimize the impact of most of the alphas. We'll mark on the charts when the alpha was redeployed with the spread data.
A nice side effect as well -- our new live history server should be 10x faster =) Not quite sure how much faster yet as it's a new approach which should make things close to backtesting speeds.

Now that L1 Equity Quotes are available for backtesting, the next step would be a good market impact model (slippage model).
For example, when a Buy Market Order is submitted, I have to take into account not only the spread, but also the available volume at the next best bid price offer.
So if you want to buy 1,000 shares of XYZ and the current bid price is $ 100.00, but only 100 shares are offered at that price, the order will not be executed in full at $ 100.00, but will reach the next level in the order book and execute the next orders at $ 100.01 and so on.
As a result, the average execution price wil be higher than current backtesting suggests.
If you want to display it 100% realistically, you would need the complete history with the highest granularity (Tick) of the entire order book (Full DOM = Full Depth of Market, i.e. Level 2 Data). You can imagine that this would pose completely new challenges to the hardware performance as the data volumes would be enormous. Therefore it makes sense to work with models that are very close to reality.
Quantopian offers various slippage models for this. I personally prefer to talk about market impact models as this is also common practice in the scientific literature.
As you can see in the documentation here, the Alpha Streams Brokerage Model uses a constant Slippage model.
So my question is: Since we now have L1 Equity Quote Data, I wonder if it wouldn't be possible to create better/more realistic Slippage Models based on that data?

Edit: Edit: A good approach would be the square-root formula for market impact, which we can use now where L1 Quote Data and thus the Spreads are available.

Hi Arthur,
Interesting suggestion. Users will find our documentation on creating custom slippage models useful when implementing this.
To go forward with this, I recommend starting a new forum thread where alternative slippage models can be discussed. Such a discussion is out of the scope of this thread.
Best,
Derek Melchin

Hi Jared,
do you have an estimated release date for the L1 Equity Quote in live mode?
Thanks

Now that L1 Equity Quotes are available for backtesting, the next step would be a good market impact model (slippage model).
For example, when a Buy Market Order is submitted, I have to take into account not only the spread, but also the available volume at the next best bid price offer.
So if you want to buy 1,000 shares of XYZ and the current bid price is $ 100.00, but only 100 shares are offered at that price, the order will not be executed in full at $ 100.00, but will reach the next level in the order book and execute the next orders at $ 100.01 and so on.
As a result, the average execution price wil be higher than current backtesting suggests.
If you want to display it 100% realistically, you would need the complete history with the highest granularity (Tick) of the entire order book (Full DOM = Full Depth of Market, i.e. Level 2 Data). You can imagine that this would pose completely new challenges to the hardware performance as the data volumes would be enormous. Therefore it makes sense to work with models that are very close to reality.
Quantopian offers various slippage models for this. I personally prefer to talk about market impact models as this is also common practice in the scientific literature.
As you can see in the documentation here, the Alpha Streams Brokerage Model uses a constant Slippage model.
So my question is: Since we now have L1 Equity Quote Data, I wonder if it wouldn't be possible to create better/more realistic Slippage Models based on that data?

Hi Arthur,
Interesting suggestion. Users will find our documentation on creating custom slippage models useful when implementing this.
To go forward with this, I recommend starting a new forum thread where alternative slippage models can be discussed. Such a discussion is out of the scope of this thread.
Best,

Hey Dave, we have finished the code changes required to maintain backward compatibility but didn't want to deploy it on the weekend. We've now got the data, code, and new tests in place and will re-deploy Monday-AM.

Sorry Dave still delayed; please subscribe to notifications and I'll update this thread as soon as its pushed. We found differences in the ticker symbology and are mapping the tickers back to the current QC format so the data should be nearly identical and not require changes to your code.
It'll likely be 1 day of engineering, 2 days of data processing and then 1 day of retesting. ETA Thursday-Friday.

Hi Jared/QC team,
I have noticed that there is access to ask/bid prices in research notebooks for second resolution.
However, I could not access to tick data - is there any work still in progress or the problem is in my code?
Also, is ask/bid data is already available during backtesting?
Thanks, Grigori.

Hey Grigori! Yes, it was deployed quietly yesterday.
Tick data is also available but it is not the same format as QuoteBars, each Tick has a TickType attached to it. The value of TickType.Quote marks ticks which are bids/asks. These are presented as a list for a specific moment of time.
Our tick data for Equities is now also timestamped to the millisecond! Previously it was rounded down to the previous second
--.
Live Trading does not have the new quote feed yet -- we're working on that and it'll be installed in the next week or two. We're literally waiting on physical delivery of some 10GB fiber modules and with the virus, everything is moving slowly.

Trying to access Resolution.Tick through qb.History() call gives me the following exception:
"Exception : cannot handle a non-unique multi-index!"
Still did not figure out the root cause, the date range seems valid (couple of hours) and it worked before.
Could you please help me on this?

I've been testing the quoteBars in slice with some low volume ETFs I follow and the availability of bid/ask improves the information content gathered from these price series. Thanks for the continuing improvements to the site. When do you see this data being available for live trading? Thanks, Hugh

Thanks Hugh;
All going well - we'll do the installation of the new live feed this weekend. We've wired up a brand new rack and are just waiting on a cross-connect cable install for the new data feed. Old live algorithms will need to be stopped and redeployed to move to the new infrastructure.

Laurent Crouzet
Jared Broad I really think it will be an important and a very useful development for QC and the QC's community that all algorithms (those that are working and the new ones) use the new bid/ask structure!
If I understand well, that would also imply that all currently validated Alphas (those on the marketplace) will be stopped and redeployed, right?
Does it also mean that it would deplete the portfolio (cancellation of all insights) of these Alphas? Or as long as everything goes smoothly during the week-end (as no market is open), the Alphas will still keep their current investments?

Pleasure Hugh!
Laurent: All QuantConnect backtest algorithms currently use spread, and soon live trading will as well. Once the new live feed is installed Alphas will need to be stopped and redeployed. An Alpha should reinitialize its state in the event of a shutdown, so it should resume their previous positions. When we eventually restart them we'll do it after market close; before universe selection; on Friday. This should minimize the impact of most of the alphas. We'll mark on the charts when the alpha was redeployed with the spread data.
A nice side effect as well -- our new live history server should be 10x faster =) Not quite sure how much faster yet as it's a new approach which should make things close to backtesting speeds.
