Insiders love to see your order. Even if your input or output is done mentally, they know where it is. They are very aware that people place their orders. That's why the love of Fibonacci and Gann traders. They know exactly where people place their orders.
Wholes themselves is true for anyone who uses one of the indicators most commonly known. Vanish inside the moving average crossovers, and so-called overbought and oversold, regardless of whether the indicator is used to display any of these conditions. They know that when prices have reached the outer limits of the Bollinger Bands, and they know the location of the alleged support and resistance, etc, but spreads have no idea of the location of their orders. You are in a market long and short in another. His position is invisible to those inside. You can not run your stop, because it has one. You may not place a stop order on the market when trading spreads! Its starting point is totally mental, but exists only in your head.
In this sense, trade spillovers are a purer form of negotiation. It's the closest thing in the trade to have a level playing field. Could be the reason why almost never hear about the spread trade? Liquidity: The attempt to trade in "fine" illiquid markets is one of the surest ways to find and stop the serious running strange price movements. However, other than occasional problems with getting full, the spread trade is not suffering from a lack of liquidity, which in itself creates more trade opportunities.
