Referring to RSI of SPY from custom order

[RajPatel]

Hello experts,
I am new to TOS and find this site really valuable for my learning. Thanks to everyone contributing here.
I have a question about setting a custom order for a symbol. In addition to the conditions on the data related to the symbol, I need to add an additional condition that checks the value of RSI of SPX.
I am able to check VWAP value by using VWAP(Symbol="SPX") but not able to find the syntax for fetching RSI value of SPX. Can someone please help?

Thanks,
Raj

plot RSI = 50 * (ChgRatio + 1);
