Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 75% of retail investor accounts lose money when trading spread bets and CFDs with this provider. You should consider whether you understand how spread bets and CFDs work, and whether you can afford to take the high risk of losing your money. Professional clients can lose more than they deposit. All trading involves risk.
The value of shares, ETFs and ETCs bought through a share dealing account, a stocks and shares ISA or a SIPP can fall as well as rise, which could mean getting back less than you originally put in. Past performance is no guarantee of future results.

Question
Guest Benjamin
When I first began to use the IG REST API, I believed that EPICs were unique instrument identifiers: that a given EPIC would always correspond to a specific instrument and that this instrument would never change.
However, I have recently discovered that this is untrue. For example, there are 19 daily Japan 225 tunnels available, which always have a set of corresponding EPICs of the form BT.D.NIK._.IP, where _ can take a value from 1 to 19. However, the size of tunnel specified by any given EPIC changes. Last week, BT.D.NIK.1.IP was +/-120 points, at the time of posting this it is +/-160 points.
This causes issues and opens questions.
I need to make sure that I am analysing the correct data and opening the correct positions.
