ES vs SPY indicator

[shodson]

Has anybody seen or developed an indicator that would graph you the ratio spread between an index future and a correlated ETF, like ES vs SPY, or NQ vs QQQQ, or YM vs DIA, etc? This could provide some cool arbitrage opportunities. Is something like this possible in NT 6.5? If so I'd like to pursue developing it.

shodson, I agree this would be an interesting approach - but have so far not seen it surfacing here. This can be done in 6.5 in a MultiInstrument strategy - http://www.ninjatrader-support.com/H...struments.html

For NinjaTrader 7 the same multiseries concept is expanded to include indicators as well - http://www.ninjatrader.com/webnew/NT7/NinjaTrader7.html
