Have you seen this before? What does that mean ? - page 2

You buy at the Ask and sell at the Bid. So your sell order's TP/SL, and pending buy orders will be triggered when the Ask reaches it. To trigger at a specific Bid price, add the average spread.

The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools -> Options {control-O} -> charts -> Show ask line.)

Well correct me if I'm wrong : 
for a long : in @ ask / out @ bid 
For a short : in @ bid / out @ ask 
Is it alright whatever is the spread ?

Correct, and now you know the answer to your original question.
Icham Aidibe: but why is the blue one shifted ?

Indeed I moved toward my real issue.
