Quote from AK Trader123:
Vision Trader (or anyone trading the ER2 Automated),
Thanks for your posts... I am new at perfecting automated strategies and have finally cornered the best settings for our specific set of parameters in the ER2. I will go with either the 89 tick or the 110, but have tested 144, 55, 233 and several other timeframes.
Here is my question. How much of a factor is slippage?
I am using Tradestation and RJO as well, and have not actually started the automation process yet. I hope to do so this week. Do you use a factor for slippage in backtesting your strategies? I've heard everything from slippage being as bad as 1 tick loss per side ($20 loss per trade), to 1 tick lost in every 5 round-trips (about $2 per round-trip trade).
So far our strategies are backtesting out with very smooth equity curves...some of them over $45K per contract over the past year (granted...this is not figuring anything for slippage...but does include commissions). They are built up of a lot of trades....between 3000 and 4000 per year. This is why slippage is such a concern to us.
Would love to know what your experiences have been....and those of others also....Thank you!

In my testing I used $20. One tick on each side. If I had to give you a number to test with I would say use at least $50 and if possible use $75 based on real world. My strategy only takes one trade per day if conditions are met....so slippage is not that critical (although costly at the end of the year). If you are moving in and out of trades several times per day than it will be an issue.
