Hey everyone, I'm relatively new to algo trading and could use some experienced eyes on a Pine Script strategy I’ve been building for the NQ. I initially ran a deep backtest with zero friction and it looked a little too perfect. Based on common advice, I went back and stress-tested it: I added $5 round-turn commissions and 2 ticks of slippage, and broke the testing down across different time horiz…

Anyone know of any studies where someone has compared the slippage with various brokers by using their API? I'm particularly curious schwab, centerpoint, lightspeed, tradestation, tradier, moomoo, ibkr. Strong interest in seeing real data comparing 'free' brokers with pay per share to see if the premium brokers save at least the amount of slippage to make it worthwhile. If i were conducting the te…

What’s the typical slippage for market orders in U.S. stocks? For a normal retail trade size of around $10k–$100k, how much slippage should I expect in stocks with about $10M vs. $100M in average daily dollar volume (trading intraday, not at open or close) Does anyone have experience or data on this? I am thinking about just focusing on stocks with $100M+ daily dollar volume to reduce unnecessary …

Quick question for those who actually trade live—how are you guys factoring in the "backtest-to-live" gap? I realized my win rate was basically a lie because most simulators use "perfect fills." They don't show the spread expansion or the fact that getting filled at the exact tip of a wick is impossible in a live market. If you have a tight SL, that 1–2 pip "slippage tax" basically kills the edge.…

Considering running scalping EAs and there's a VPS provider promising 1ms-5ms latency to broker servers. Wondering if that kind of speed actually makes a real difference in slippage, or if it's mostly marketing hype. Also curious—has anyone had success using scalping strategies for copy trading? Seems like execution timing would be an issue, but wanted to hear from those who've tried it.
