V = Volume weighted average price A = Arrow (price crossed VWAP) B = Bell (price touched VWAP)
Instant entry when a bell shows up after arrow.
At 29 July 2021 0800 hours UTC+7 in a EURGBP 1h chart, the VWAP (Volume-weighted average price) line turned from purple to white. The price crossed above the white VWAP with a green arrow.
At 10.00 hours, the price came down to touch the white VWAP line and a bell showed up. With these conditions (Vwap-Arrow-Bell) in place, a buy order could be sent out the instant that the bell appeared. If the leverage was 1:500 and the lot size was 20% of the balance, a cautious trader could take profit when the fund grew up beyond 4%.
