Just for understanding:
Slippage is the difference between the quote you get with last tick and the price you pay with next tick, when you place the order. Some brokers offer to execute without slippage but I would never trade there.It would be suicide for the broker if he sell at quote price if the market prices moves away very fast. It will open the door for arbitrage trading.
What can you do?
- At first there is a slippage allowance in the buy and sell blocks. That mention you can limit the slippage on order execution. If the market is more away than ... your order will not become executed.
- Place pending orders and allow a small slippage. You can look for brokers who guarantie to execute pending orders at the given price (maybe on some conditions)
No slippage will only work on slow market movements, thats why lets say you place pending order at 1.11111 and one tick the market is at 1.11110 so the order is not triggered yet. One tick later the price is at 1.11112 and without slippage the order will not be triggered because the price is away. In fast moveing markets (the only markets to make profit) its hard to hit exactly your price.
