I look at the fib numbers from recent high lows Dec 13, 358 Marc 8, 428
Fibs 410.5 62% 399 50% 391.5, 383,
High march 428 to low 371 May Fib 399 50% , 62% 405
RTR closed above 400 yesterday and tested it today .This indicated that this may be the new support line/level for day trades.
Resistance today was 405 with 410 as the next resistance
415 was the possible target for today based on the low of 371
Once the resistance lines are broken it is said that they provide support.
Looking at RTR the ema provides a guide to support and resistance having worked out the possible targets .The candle shapes provide further indication of movement.Using this theory rtr may bounce from 405 with further support at 400
I am sorry about the note form of the info ,but a little busy at present
