i'm a little bit confused.
if there is no weekend candle than weekend-trades do not exists. if, like it is written in the manual, i execute a trade at the opening of every candle, then there should not be a problem with this.

the usual process in my mind is (daily-strategy):
1. new candle opens (Friday)
2. run code and check for conditions.
3a If conditions are TRUE open trade
3b if conditions are FALSE wait until open of next candle, in this situation the Monday candle at first open-tick and process with number 2.
4. During the course of a candle check conditions for TP, TS or SL.

in simple every markettick is like a cpu tick.

process, evaluate, calculate data
output data (trade entry, TP, SL, TS or exit)
