I'm still learning Quant Connect, coming from a Metatrader background.  One of the things that are a bit irritating is the fact that I cannot visually validate if my coded logic is working as intended.  Meaning there is no proper chart to visually inspect buys/sells + indicators to see if it's doing what it's supposed to do.

That being said, I'm manually looking at timestamps with a chart on TradingView to see if the logic is working as intended.

An extremely simple strategy to test this is to buy at close of upper Donchian channel and sell and close of bottom Donchian channel.

What I'm finding is the values don't align with what I see on the chart. For example, this buy and sell trade:

+2021-04-30 12:00:00BTCUSD Buy Market Fill: $57,109.00 USD 1.73591166Filled 

+2021-05-10 16:00:00BTCUSDSell Market Fill: $55,770.00 USD -1.73591166Filled Liquidated

For starters, the timestamp does not reflect the correct entry point however the price is correct.  TradingView shows 16h00 whereas it shows as 12h00 on the order details.  Then, the closing trade is way incorrect.  It should have closed on 2021/05/04 00:00.  However for some reason it was sold on the 10th, 6 days later.

So my question… is my logic incorrect (am I not understanding something properly) and what is the easiest way to visually validate if logic is working or not ?
