data length in Barstate.ts is wrong?

[dcaoyuan]

in Barstate.ts, the length of data is determined by this.context.data.close.data.length, but per my debug, this.context.data.close.data.length is always the same as current idx, seems the this.context.data.close.data is gradually added.

I think we should use this.context.length.

there are still many inconsistencies in barstate, I'll need to a full pass to compare all the values with tradingview's
