Streak lets Zerodha users build rule-based strategies without code, backtest them and get alerts to confirm trades — and it is free for Zerodha users. VolumeLens is built for traders who decide each trade themselves: a visual scanner, order flow charts, AI analysis of the chart, and trailing stops once the trade is on.
Streak is a no-code strategy platform integrated with Zerodha. You build entry and exit conditions from dropdowns, backtest them, and deploy them to watch the market.

Build a scan with point-and-click filters, backtest it on historical daily data, and turn on alerts for it — without rebuilding the conditions.

Footprint charts, cumulative volume delta, volume profile, a depth ladder and large-trade markers show what traded inside each candle — a category Streak does not cover.

AI Mentor and Market Eye describe trend, volume levels and order flow in plain language or voice. They explain what the data shows; they do not tell you what to trade.
With a connected Zerodha or Groww account: step entries of two or three staged orders, GTT OCO for stop and target, and trailing stops by percentage or in steps with an optional breakeven lock — every update logged.
Streak suits traders who want to express a strategy as rules, backtest it and get alerts when the rules match — free on a Zerodha account.
VolumeLens suits traders who decide each trade themselves and want order flow, AI analysis and stop management around that decision. The two can be used together on the same Zerodha account.
