Dear Support Team,
I wrote a simple strategy in order to see the GetHistoricalCandle function "in action". But something is wrong because the strategy didn't make any trade.
Where did I make a mistake?
Thank you in advance.

Hi,
This is actually due to that the last candle data (OHLC) are not yet retrieved when the candle starts. When the flow reaches the IF block after 10mn (or any candle period defined), the last candle (which is the current candle under construction) did not get assigned yet with its data. This is mainly due to the way the candles are built technically speaking.
If you need to compare 2 candle data, it is more accurate to do it using 2 "finished" candles (i.e Shift 1 and Shift 2 for instance) therefore, you are sure to use candle's high price that is permanently assigned and not a high price that still fluctuating along with the candle construction till the candle's period is over and the final data is attributed (we're talking here about High, low and close prices as the open price is the first variable to be assigned).
Hope this clarifies things ...
Cheers
