The problem with using a trailing stop through ig markets when cumulateorders=true is that it calculates on the average entry price, something IG markets doesn’t allow. Using a pending order applies to the individual positions but still stops them all at the same level and importantly mid way through the price bar and not calculated after the candle is formed, hence managing the risk much better as positions often get stopped out during volatility.
This is from IG markets
“After discussions with ProRealTime it has been decided that ProOrder for IG will not calculate on average entry prices but be based on the individual positions entry price. This has been decided to avoid frequent updates to stops and to avoid stops being rejected at less protective levels than before because of the minimum distance being taken into account at the time of update. “
