GBPUSD 150-200 Pip Short

Very early in the trading range in a Wyckoff cause phase. However there is a very large institutional candle where positions could be unloaded at the beginning of that candle, selling off to the bottom of the trading range between 150 and 200 pips. The Institutional candle didn't break the Buyers Climax high so I don't expect the next phase to break the Institutional candle high. Instead we should see an instant reaction as the volume of the sellers have grossly oversold with a very little volume candle. Additionally, the RSI divergence from the Spring to the Institutional Candle/Upthrust suggests that the price will fall as we're still on the high side of the buying on the RSI. The best part is the risk to reward is 7:1 ratio. GBPUSD Apologies for the text all over the chart, but this is how I chart. Any Wyckoff Method traders that have any input, please share.

The basics of Elliot Wave would've told me that the current call was a short pull-back.
