Anyone have ideas on how to fix this?
GBTC data charts correctly, and BTCUSD data charts correctly, and the BTCUSD* xxx - 1 plots correctly. But when GBTC is placed 'above', it no longer shows anything other than -1.000
0.00100231 is the amount of bitcoin per share in GBTC according to the grayscale website= https://grayscale.co/bitcoin-investment-trust/
Multiply that by the real price of bitcoin and you'll get the net asset value per share of GBTC. Divide GBTC last trade price by net asset value per share of GBTC and you'll get GBTC premium to net asset value expressed over 100%(maybe 150%)... subtract 1 and youll get premium to net asset value expressed properly..
For example if Bitcoin is $7350 and GBTC is $11.93, premium to net asset value is 11.93/($7350*0.00100231)-1==0.619 or GBTC is trading at around a 62% premium to its net asset value.
bitcoin per share on GBTC has changed slightly since i made this chart due to inflows/outflows from the fund, management fees, etc., but again, underlying themes of the chart remain the same.
