The SL to be set to BE issue has been fixed in the Trade Copier v1.1, so it will be set correctly all the time.
The other question is a good one and I will explain the reason for the observation you have.
The main idea is to keep the TP/SL levels of the signal AS THEY ARE ORIGINALLY and not to change them.
I will explain with an example, a signal comes
EUR/USD
Trend: Upward
Buy@ 1.3903 Target 1.3933 Stop 1.3873
Supports: 1.3914 - 1.3866
Resistances: 1.3951 - 1.3999
Because of the delay when you get the signal and the market volatility the Trace Copier opens a trade late with let's say 4 pips at 1.3907, as explained TP/SL will stay the same 1.3933(+26 pips TP) and 1.3873(-34 pips SL).
You ask why? Because if we change the SL to be 1.3907 minus 30 pips = 1.3877 and you can see that 1.3877 > 1.3873, if the trade goes in the wrong direction it will be closed before the original signal SL, but it is possible that a trade may reverse in a positive direction at 1.3874 and then WE MAY CLOSE IT IN PROFIT, as such we will REPORT this on the site AS a PROFITABLE TRADE, but in reality for the people with SL at 1.3877 this will be a lost trade and they will accuse us that our stats are not correct! As you can see the reason is simple, in order to keep our stats correct and our customers to get a consistent picture we have to follow this rule. Nothing can stop you to manually close the order at 1.3877 if you want, right!?
.
If you enter a trade before the signal Target is hit, we follow a different approach,namely the idea is to get these 30 pips and close the trade in profit as soon as possible.
Here is the example, a signal comes.
GBP/USD
Trend: Upward
Buy@ 1.6124 Target 1.6154 Stop 1.6094
Supports: 1.6135 - 1.6087
Resistances: 1.6172 - 1.6220
You open a trade 3 pips earlier at 1.6121, than the TP will be 1.6151 and SL will be 1.6091, i.e. you exit as soon as you reach 30 pips and your SL is exactly 30 pips.
Hopefully all this notes will shed light how the Trade Copier is working. If you have better ideas I am ready to listen and we are always open for discussion.
