Trading View and Quantconnect not matching up

I am running a basic MACD crossover on the EURJPY. I am looking at when the insights are emitted, and it doesn't match up with the Trading View chart. Not only that, the insight summary is showing different dates than the insight count chart. 

From the trading view chart of the EURJPY with daily resolution, there should be an insight emitted on Jan 2, 13, and 21. The algo emits insights on Jan 1, 4, 13, and 23 on the summary and Dec 30, Jan 6, and 20 on the chart. Why?

I have put a log message in the Update function in the Alpha Model and it seems it is only getting new data sporadically, about once every 2-20 days. The resolution is set to minute and there is a daily consolidator. What is happening?

Hi Tamim Fund,

It's common for TradingView algorithms to have slightly different results compared to LEAN. This is a result of differences in the data used to run the backtest.

As for the discrepancy in dates between the Insight Summary table and the Insight Count plot, I've forwarded this bug to our UX team to resolve. Thanks for reporting it.

In regards to the second post above, it appears the Update method is only being called sporadically because of this logic:

direction = InsightDirection.Flat

if sd.MACD.Current.Value > sd.MACD.Signal.Current.Value * (1 + self.bounceThresholdPercent):
direction = InsightDirection.Up
elif sd.MACD.Current.Value < sd.MACD.Signal.Current.Value * (1 - self.bounceThresholdPercent):
direction = InsightDirection.Down
if direction == sd.PreviousDirection:
continue

algorithm.Log(f"time: {algorithm.Time}... ")
sd.PreviousDirection = insight.Direction

In the above snippet, the log is only hit when the insight direction has changed. If we moved the log to the top of the method, we'd see it's receiving minutely data.

Best,
Derek Melchin
