Contract specifications on CSI

Hi. I have a question regarding contract specification in CSI data for backtesting purposes, is it best to use the back adjusted option in CSI data settings or use nearest futures, or a different setting please? For example on back adjusted Crude Oil had a high of $98 a couple of months back but the real high of $80 was only achieved last week.

Therefore if you are using a long term trend filter then 1 option would give a long signal on the filter and the other would give a short signal so it's quite important.

Any comments on this subject would be appreciated please.

You have to use backadjusted contracts for the trade P&L to work out correctly. This also simulates exactly what you would have experienced in actual trading -- trade what you test and test what you trade.

Trading Blox also makes available the unadjusted close that can be used to check for new all time nominal highs.
