Hi Guys,

So far the help on here has been really useful and I have been able to build a basic algorithm. However, when I backtest and look at the trade log, the trades seem to happen at unexpected times.

Take this backtest. The first buy order triggers at 2018-03-01 14:00:00 (image 1). If I go to Oanda and look at their chart, the requirements for a buy order are not met:

Fast EMA is not above Slow EMA, and RSI is less than 40. Also, the backtest price seems way off the market price.

There is a similar case for closing the trade too. The first trade was closed at 2018-03-05 03:00:00 (image 2).The fast EMA is not less than the slow EMA. Again, the order price seems way off the Oanda chart price.

Can anyone tell me where I am going wrong?

Hi,

When you're debugging this, make sure you know what timezone your Oanda charts are displaying the data in, as well as what timezone QuantConnect is displaying trade times in. I would think a difference in timezone explains the behaviour you're seeing.
