EXTERNAL RANGE LIQUIDITY TO INTERNAL RANGE LIQUIDITY:
THE KEY TO BIAS
now what is external range liquidity (ERL):
External range liquidity is simply the previous high or low.
What is internal range liquidity:
Internal range liquidity are FAIR VALUE GAPS Or FVGs (the gap between 2 candles)

NOW PRICE ONLY DOES 2 THINGS!
Go from ERL to IRL
As we can see here, price hits a PD ARAY then gos to ERL once it hits ERL it gos back to that IRL (the FVG) and continues to do so (PD ARAY'S are higher time frame levels like supply/demand zones, FVGs and orderblocks)

So in short ERL and IRL are draws on liquidity needed for market to go up and down.
Now how do we add that to our trading!
So if we hit a bullish PD ARAY and ERL is taken once it retraces into IRL we can zoom into lower time frames for our set ups as an entry.
This works just like supply and demand we use higher time frame bias to enter on lower time frames
