TRX dropped below the lower trend line (to a low of 508), which I put down to BTC's drop from ~8050 to ~7920. I expect TRX will bounce back above the lower trend line just as soon as BTC goes sideways or upwards again.
BTC may drop as low as 7500; in which case, I'd expect TRX to continue downards (maybe sub 500), although this would be temporary!
