Crypto Buy-Dip, Price Percentage Delta- Top 1% of Community.

Framework Description

The framework allows experimentation with, and utilization of, two fundamental properties. Those properties are trend and curvature of price. For example you may wish to select instruments that have been trending downwards and curving upwards, or some other mix of trend and curvature. The changes1Ratio variable determines the influence of trend. A positive changes1Ratio will increase the tendency to select instruments that have been trending upwards, a negative changes1Ratio will increase the tendency to select instruments that have been trending downwards.  The changes2Ratio variable determines the influence of curvature. A positive changes2Ratio variable will increase the tendency to select instruments with a price that has been curving upwards. A negative changes2Ratio will increase the tendency to select instruments with a price that has been curving downwards. You can also set either the changes1Ratio or changes2Ratio variable to zero. This will eliminate the influence of that variable. So if you just want to select based upon trend with no regards to the curvature you would set the changes2Ratio to zero. Magnitude has the obvious effect. A large magnitude of changes1Ratio combined with a small magnitude of changes2Ratio will produce an algorithm that mostly considers trend with regards to instrument selection. Both the trend and curvature considerations are exponential in nature. So more recent events will have a higher influence upon selection than older events.
 

The emaOfChanges1Indicator indicator is the primary indicator of trend. It holds an exponential moving average of the changes in price. You can change it's length by adjusting the emaOfChanges1Length variable. The emaOfChanges2Indicator indicator is the primary indicator of curvature. It holds an exponential moving average of the change in change of price. You can change it's length by adjusting the emaOfChanges2Length variable.
 

Hey Warren, 

Have you tried trading the strategy with other instruments? Just wondering it's robustness, I have another strategy that works great on crypto but not so well on other instruments. Meaning the crypto community might be naive and technical indicators and strategies still have high impact. 

Hi Elsid,

Ya, crypto is a newer space for algo developers so I've been looking at it as an opportunity before it's swamped with more refined analysis. I do have a volatility algo that operates on similar principles as the framework here, It profits well. Results with equities might be less than stellar. Fundamentals seem to do well there.

Hi Jared,

I see you changed the headline for me. Thanks, except that it's not an EMA cross. It might be better described as a buy the dip algo. Or, as I've called it, 'the framework'. Or simply a 'crypto algo'. 

Hello everyone,

I'll explain more thorughly how the algo operates. It doesn't really have a name because it operates on principles that I invented myself. I may not be the original inventor but I haven't seen these principles in common use. The primary trend indicator calculates the ema of the percentage changes in price. Note that it's an ema of percentage change in price, not the usual ema of price. This allows one to assign a single number to 'trend'. This number is based upon percentage change in price, so you can readily compare with other instruments to find the instruments with highest or lowest trend. Because it's an ema, more recent changes have a greater influence than less recent changes. The primary curvature indicator operates in similar fashion, but it takes an ema of the change in change of price.

How's that? ;) Fixed it.

Excellent. Thanks Jared!

Hey Warden, 
I converted it to limit order but the return has a significant drop compared to the initial one. Any idea what might have affected the algo?

Thanks

Hi Nick,

A few things come to mind, though I haven't examined your algo in detail. The Liquidate call will have to go as well, it uses market orders as I understand it. You might want to cancel the limit orders if they don't go through, possibly after some amount of time. This could be why the returns have come down so much, though I haven't checked thoroughly. I'ld have just used the bid price for purchases and the ask for sales given the behavior of the instruments on GDAX. If you go to the GDAX exchange you'll see that there is practically no spread. If you set a limit order at the ask for a purchase I'm not sure if you'll meet the 'maker' requirement for fees on GDAX, which is going to be critical for this algo.

Has anyone figured out a good algo for GDAX maker orders for this algo?

Hello everyone,

I attempted to launch the code "live" at OANDA, but it gives the following werrror. Could any one tell me what is missing in the code to go live?...Thank you!

Failed to initialize algorithm: System.Exception: No default market set for security type: Crypto at QuantConnect.Algorithm.QCAlgorithm.AddSecurity[T] (QuantConnect.SecurityType securityType, System.String ticker, QuantConnect.Resolution resolution, System.String market, System.Boolean fillDataForward, System.Decimal leverage, System.Boolean extendedMarketHours) [0x00036] in <321054ea1e964454bc0d403925dda91a>:0 at QuantConnect.Algorithm.QCAlgorithm.AddCrypto (System.String ticker, QuantConnect.Resolution resolution, System.String market, System.Boolean fillDataForward, System.Decimal leverage) [0x00001] in <321054ea1e964454bc0d403925dda91a>:0 at QuantConnect.MultiCoinFramework.Initialize () [0x00067] in <0e4d1f8fc06a43f2a3bc45c24a3f6958>:0 at QuantConnect.Lean.Engine.Setup.BrokerageSetupHandler+<>c__DisplayClass24_0.b__1 () [0x000fb] in <7a802d713401490dbae6b34efb125c68>:0

Has anyone had any success live trading this on GDAX? I'd be curious to see how the actual results pan out with a market order or even a limit order.

hi Alexandre Catarino & Jared Broad 

i wanted to play around with warrens code and see how it behaves with stocks but got a runtime error.

1) could you please help me find it? IT DIES ON

 2017-03-21 00:00:00 :Runtime Error: Cannot perform runtime binding on a null reference

edit the date first!!!!!!!!!

2) where did the VRX data go? :)

thx

I have tried to run a similar stragety live, and it buys the sells the first order great, but when it goes to buy the second it says invalid because of insufficient buying power, Does anyone have any ideas?

As of this afternoon, the strategy does not work if more than 1 crypto is in the string. Was working fine from yesterday through this afternoon.  If 2 only are on the list, ETHUSD, BTCUSD or BTCUSD, ETHUSD, the 2nd listed pair will fail with this error:

Runtime Error: 'BTCUSD' wasn't found in the Slice object, likely because there was no-data at this moment in time and it wasn't possible to fillforward historical data. Please check the data exists before accessing it with data.ContainsKey("BTCUSD") (Open Stacktrace)

This algo now fails! I hacked in a quick 'data.ContainsKey' and 'continue' thinking that would solve the problem and the returns dropped dramatically. Anyone at Quantconnect know what happened? Sounds like odd behavior given Thushara's report.

Warren i think Jeremy might found the problem.

data is null so the indicator and everything might be dead?

you could of course write to support@quantconnect  :)

my english is really bad :):) hehe

Some temporary data issue? seemed to impact the algos which subscribed to more than one pair.

It seems to be working again.

Nevermind OP's code works if you add the actual ticker string instead of the Symbol:
