To make it totally clear, when an AT 300 ‘buy’ trade went through, both the Bid and Ask prices would be raised on the next trade that was made, similarly on an AT 300 'sell' trade, both Ask and Bid prices would be dropped on the next trade that was made.
With the AT 500 trades, if it was a 'buy' the Ask would be raised and the spread would be widened upwards on the next trade and if it was an AT 500 'sell' trade the Bid would be lowered, widening the spread downwards on the next trade.
And these were all blatantly obvious signs and thses signs only occurred with AT trades.
