I want to edit lows on symbols that had momentary spikes that show up as legitimate dip trades, but in fact were never humanly tradeable. I want to make dip-script simulations more realistic.

I searched Wiki. Also saw a posting from 2006 that WL 4.x had a Data Editor in Data Manager, but have not found similar feature in 6.0.

Can someone share how to open the .WL data files so I can edit occasional lows?

Thanks in advance

Hi Ted, just open the Dialy chart and double click the bar you want to edit. The Bar Data Editor will appear.

Perfect!

Thank you Robert

Cone & anyone else interested.
Thought you might be interested in the results (after editing lows that were momentary spikes down).
I ran my dip model(signals generated from EOD daily close data) on the Russell 3000 (RP mode to identify all possible trades) going back 12 months.
I then examined the 1min bars on every profitable trade > 3% (~700 trades). Whenever, I found a trade that had triggered an entry on a momentary spike down (1-2mins in duration).... I edited the daily low (based on 1min bar data)to a realistic point where trader could actually have had time to react. Altogether, I found roughly 150 momentary spikes, then daily lows were edited higher to a level that the 1min data suggested a trader could have reacted to & gotten a realistic fill.

Net,net the ave P/L% per trade was 1.97%(one day hold) before the editing of the daily lows and 1.79% per trade after daily lows were raised(momentary spikes removed). Win% & Profit Factor also had miniscule reductions. Scouring thru the 1min data was a long & painstaking task. But provided the answer to a mystery most of us dip traders have long wondered about.
Yes,occasional momentary spikes (that cannot realistically be traded) do inflate Stats.
But, in my case, only by a small amount and not enough for me to alter my model in any way.

Robert & Eugene, thanks for your tireless support. WLP 6.0 is a dream come true.

Ted, with Auto-Trading why don't you think those "real" spikes can be bought? After all, it only takes 1 tick below, say, a 98% trigger threshold to put a limit order in the market as the price falls through the limit price. It's even likely that the 2 or 3 seconds of delay that it takes to get the order to market, you'll even get filled at a better-than-limit price.

Nonetheless, it's always good to be more conservative when backtesting :)

Three reasons I cannot use Auto-Trading at this time (although I hope it becomes practical for me one day):
1) I trade 3 separate accounts and it's easier to manually place 1 Block trade thru Advisor Channel than Auto-Trade 3 separate accounts (Quote tool tracking 9000 Limit orders(3 accts) instead the 3000(1 block acct) I do now).
2) I never trade Earnings Releases(2 days before nor one day after), so I always validate this fact before allowing a trade to take place. This will be resolved in the next Community.Components update (which includes EPS dates updating more frequently).
3) I never trade stocks that open < 5% above entry limit level. Requiring me to manually validate this & avoid auto-trading. This will also be resolved in an upcoming WLP release that will disallow those trades for me.

Finally, you nailed it. I am extremely conservative in my back-testing. In live trading manually, my experience has been that spike downs lasting < 1min seldom get even partial fills & those lasting 1-2mins end up being tiny partial fills. Perhaps the most significant factor is size of my trades which can be up to 1% of the 10day Ave Daily volume.

All the best,
T!
